(1814) Netherlands East Indies (Indonesia) 1 Real Batu with Sumenep Counterstamp on Mexico Philip V Cob 8 Reales (1711 or 1712)

Specifications:
27.07 g, 0.917 fine, .798 troy oz (actual silver weight)
Recorded mintage: unknown
Catalog reference: KM 197 (KM 47a host coin)

Details:
Madura is a small island lying just off the northeastern tip of Java, and Sumenep its easternmost and most culturally significant sultanate. From the early nineteenth century until the Japanese invasion of 1942, both fell under Dutch colonial administration as part of the Netherlands East Indies, though the degree of that control, and the autonomy local rulers could exercise within it, varied considerably across the period.

In the early nineteenth century, the island of Madura faced a problem familiar across much of Southeast Asia: an acute shortage of reliable silver currency. The Dutch colonial financial system that had structured monetary life in the region for generations had been thrown into disarray by the Napoleonic Wars, and Raffles's British occupation of Java beginning in 1811 did little to stabilize it. Into this environment came Sultan Paku Nata Ningrat, who had assumed rule of the Sultanate of Sumenep, the easternmost region on Madura, just north of Surabaya, that same year, and who responded with a countermark program of considerable practical ingenuity. Sumenep struck no coins of its own, depending entirely on the eclectic mix of foreign silver moving through regional trade: Dutch ducatons, Indian rupees, Maria Theresa talers, and Spanish colonial cobs that had been circulating since the previous century. By impressing the sultanate's mark on approved foreign silver, the court authenticated that coinage, fixed denominations, and asserted monetary authority without a mint. The host coin here, a Philip V cob 8 reales of 1711 or 1712, struck at Mexico City in the irregular cob style and worn smooth by decades of trade, was reclassified as a 1 Real Batu, batu meaning "stone," the local term distinguishing old hand-struck cobs from milled coinage.

The countermark struck on this piece bears "Sumenep" in Arabic script within a square surround, accompanied by the Hijri date AH 1230, corresponding to late 1814 or early 1815. Sultan Paku Nata Ningrat was simultaneously among Raffles's most valued Madurese collaborators, serving as a key informant for The History of Java (1817), while conducting diplomacy, Islamic scholarship, and monetary reform within the same court. The square Arabic-script type is found almost exclusively on cob 8 reales, suggesting the court deliberately paired this stamp with the older cob-style silver it was most concerned with authenticating; later oval-surround variants migrated onto Dutch coins and Maria Theresa talers as the program matured. The undated flower or "Madura Star" countermarks also associated with Sumenep remain harder to sequence precisely, but the presence of firmly dated Arabic-script examples like this one establishes that the sultanate's monetary program was already operating in fully legible, date-recorded form within three years of Paku Nata Ningrat assuming power, a striking assertion of institutional confidence amid the political turbulence of the British occupation.

(1814) Netherlands East Indies (Indonesia) 1 Real Batu with Sumenep 5 Petal Counterstamp on Mexico Philip V Cob 8 Reales (1702-1728)

Specifications: 27.07 g, 0.917 fine, .798 troy oz (actual silver weight), 26.04 g weight on scale
Recorded mintage: unknown
Catalog reference: KM 197 (KM 47 host coin)

Details: This example presents a second variation among the Sumenep countermark types: the five-petaled flower with a circular center, a motif distinct from both the shield-like Madura Star applied to larger milled coins and the Arabic-script stamps seen on the previous piece. The flower types are among the more visually immediate of the Sumenep marks, less legible as official text, but unmistakable as a deliberate stamp, and their appearance on cob hosts in conjunction with or alongside the Arabic "Sumenep" inscription suggests the court used multiple die types in parallel, perhaps at different points in the authentication process or from different issuing hands. The host coin here, a Philip V cob 8 reales of 1702–1728, carries an additional layer of history beyond its Madurese countermarking practice: its lightly porous surfaces and darkened patina are consistent with an extended period of saltwater immersion, and the coin is almost certainly a shipwreck salvage, recovered from a vessel lost somewhere in the China Sea or Philippine waters

(1828) Spanish Philippines 8 Reales with MANILA counterstamp on 1828-LM JM Peru host (Ex. Murphy / Rose / Farouk)

(1828) Spanish Philippines 8 Reales with MANILA counterstamp on 1828-LM JM Peru host (Ex. Murphy / Rose / Farouk)

Specifications:
27.07 g, .903 fine silver, .786 troy oz (actual silver weight)
Recorded mintage: unknown
Catalog reference: KM 25

Details:
The MANILA counterstamp dated 1828 was the first of Spain's attempts to bring order to the flow of rebel-inflected silver arriving in the Philippines from the newly independent republics of South America. On October 13, 1828, Mariano Ricafort, Captain General of the Philippine Islands, issued an edict directing that coins struck by the "insurgent provinces and revolutionary governments" be overstamped to obliterate the offending legends: the words REPUBLICA, INDEPENDENCIA, and LIBRE appearing on Peruvian, Mexican, Colombian, and Bolivian issues were all considered politically dangerous in a colony that Madrid was determined not to lose. The dies were prepared locally at the Manila foundry by Benito de los Reyes, with the 1828 overstrike applied using a screw press to drive a full obverse and reverse design over the original coin: MANILA 1828 within a serrated border on one side, and HABILITADO POR EL REY N.S.D. FERN. VII, "authorized by the King, Our Lord Don Fernando VII," surrounding the Spanish arms on the other.

The operation proved costly and mechanically troublesome almost immediately. The screw presses used at the foundry were not robust enough to fully obliterate the underlying design, and the 1828 overstrikes typically show remnants of the original Peruvian or Mexican coin visible beneath the new dies. Production was sporadic, with large gaps between runs, and the program was effectively abandoned by the early 1830s in favor of the simpler F.7o and later Y.II punch countermarks that replaced the full overstrike system. Surviving 1828 MANILA pieces are scarce, and the 1828-LM JM Lima sol is among the more commonly encountered host coins within that already limited population, a Peruvian republican 8 reales struck in the same year the Manila program began and presumably swept into it soon after arriving in the islands.

Incredibly rare with chopmarks, it's not hard to imagine the coin traveling between China and the Philippines, but this is the first and only example I've seen with the combination of Chinese chopmark and this counterstamp.

Spanish Philippines Ferdinand 7 Countermark on 1833-LM MM Peru 8R host coin (Ex. Murphy)

Spanish Philippines Ferdinand 7 Countermark on 1833-LM MM Peru 8R host coin (Ex. Murphy)

Specifications:
27.07 g, .903 fine silver, .786 troy oz (actual silver weight)
Recorded mintage: unknown
Catalog reference: KM 83

Details:
The Manila overstrike program of 1828-1830 had proven too mechanically troublesome to sustain, and by late 1832 Spanish authorities in the Philippines had moved to a simpler approach. A decree of October 27, 1832 replaced the full-coverage screw-press overstrike with a small circular punch countermark, roughly 9-10 millimeters in diameter, bearing a crown worked in pearls with a small cross at the top and the initials F.7o beneath, for Ferdinand VII. Die preparation shifted to Diego de los Reyes, and the punches were applied by hammering rather than screw press, a simpler process that allowed Manila to keep pace with the steady arrival of republican silver from Mexico, Peru, Colombia, Bolivia, and Chile. The political logic remained the same as it had been under the MANILA overstrike: to validate foreign silver for circulation while asserting continued royal authority in an increasingly isolated colonial outpost.

The host coin here, an 1833-LM MM Lima sol, was struck in Peru just months or perhaps a year before it received its Manila countermark. The F.7o punch remained in use until Ferdinand's death on December 20, 1834, after which the initials were replaced with Y.II for his daughter Isabel II. That relatively short window of active F.7o countermarking, combined with the program's continuation through the remaining stock of coins already in transit or circulation, accounts for the examples that appear on host coins dated through 1834. The countermarks were applied indiscriminately to coins in any condition, including heavily worn, holed, or chopmarked pieces.

Spanish Philippines Isabella II Countermark on 1834-Go PJ Mexico 8 R host coin

Spanish Philippines Isabella II Countermark on 1834-Go PJ Mexico 8 R host coin

Specifications:
27.07 g, .903 fine silver, .786 troy oz (actual silver weight)
Recorded mintage: unknown
Catalog reference: KM 129

Details:
The crowned "Y.II." countermark struck on this 1834 Guanajuato 8 reales is the product of a specific administrative crisis: the collapse of Spain's Latin American empire and the flood of newly republican silver it sent into the islands. The Manila galleon trade had long made the Philippines a natural terminus for Mexican silver, and when Mexico and the other mainland colonies broke from Spain in the 1820s, their coins, bearing liberty caps, eagles, and republican legends, continued to arrive in quantity, carrying imagery that colonial authorities regarded as potentially inflammatory. Manila's response unfolded in stages. Beginning in 1828, officials applied full "MANILA" overstrikes intended to obliterate offending designs entirely, a labor-intensive approach abandoned by 1830. A simpler "F.7o" punch for Ferdinand VII followed in late 1832, and when Ferdinand died on 29 September 1833, that punch became obsolete almost immediately. The "Y.II.", for Isabel II, who acceded as a three-year-old under her mother's regency, replaced it, with examples generally attributed to 1834–1837. The countermark's purpose was as much political as monetary: it revalidated familiar crown-sized silver already circulating locally while converting republican coinage into an explicit expression of continued Spanish sovereignty.

The chopmarks on this coin add a further dimension. Philippine-countermarked 8 reales bearing Chinese merchant chopmarks are common enough that numismatists have examined the sequence carefully, and the weight of evidence (documented by Gullberg in his book on Chopmarks) suggests the chopping often preceded the Manila stamp rather than following it. This matters because Manila's countermarking fees were explicitly scaled to account for the degree of chopping already present on a coin, acknowledging that heavily chopmarked dollars were simply part of the circulating mix the authorities were trying to bring to order.

Catalog reference: Countermark: KM-440.21 Host Coin: KM-97

Details:
The crowned Portuguese arms countermark on this 1804 Lima 8 reales was applied by decree on 1 September 1834, in the immediate aftermath of one of the more turbulent passages in Portuguese history. The Liberal Wars, six years of civil conflict between constitutionalists loyal to Dom Pedro IV and absolutists backing his brother Miguel I, had ended in May 1834 with a liberal victory, but left the country's finances badly depleted. The new constitutional government, now formally under the fifteen-year-old Maria II following Pedro's death in September, faced an acute silver shortage; the mint lacked the capacity to produce sufficient new coinage quickly enough to meet demand. The solution was practical and rapid: all Spanish and Spanish-colonial 8 reales still in circulation were to be presented for countermarking and officially revalued at 870 reis, their crown-sized silver weight making them a natural equivalent to Portugal's 960 reis standard. The range of host coins that received this stamp is extraordinary; over 150 distinct varieties are documented, spanning colonial mints from Mexico City to Potosí to Lima across more than a century of production, a breadth that reflects just how widely and indiscriminately Iberian silver had spread through Atlantic trade networks by the 1830s.

This coin also carries Chinese merchant chopmarks, likely acquired after its time in Portuguese circulation as the coin continued moving through trade networks to the east.

(1841) Guatemala Type IV countermark on 1828-LM JM Peru 8 Reales (Ex. Bowman / Murphy)

(1841) Guatemala Type IV countermark on 1828-LM JM Peru 8 Reales (Ex. Bowman / Murphy)

Specifications:
27.07 g, .903 fine silver, .786 troy oz (actual silver weight)
Recorded mintage: unknown
Catalog reference: KM 118.1

Details:
The Federal Republic of Central America, formed in 1823 from the five former Spanish colonial provinces of Guatemala, El Salvador, Honduras, Nicaragua, and Costa Rica, had effectively dissolved by 1838 under chronic internal conflict. Guatemala declared full independence in 1841. The market in the years surrounding that break was flooded with silver from mints across Latin America, in varying states of wear and of uncertain fineness, with no reliable mechanism to standardize it.

A decree of October 31, 1840 authorized the countermarking of foreign crown-sized silver circulating in Guatemala, issued by the Guatemalan state government then operating under the strong influence of Rafael Carrera, the conservative military caudillo who had taken Guatemala City in 1838 and effectively controlled the government through a series of nominal civilian leaders. The countermarking itself was carried out at the Nueva Guatemala mint by the mint's assayers, with the program running from December 1840 into early 1841. The host coin here, an 1828 Lima 8 reales, is a Peruvian republican issue that had traveled north, likely through Pacific trade routes before taking on this new role.

The Type IV is the most technically refined of the Guatemalan countermark types, applied with hinged dies that struck both faces of the coin simultaneously, avoiding the flattening on the opposite side that earlier types produced. The obverse mark shows a radiant sun rising above three volcanoes, drawn directly from the Central American Republic's own coinage, while the reverse carries a sun atop a five-pointed star above a bow, quiver, and arrows within a circular incuse. The program operated for only a matter of weeks before Guatemala's full independence brought the federation's shared monetary framework to a close, which accounts for the relative scarcity of Type IV pieces compared to the earlier types in the sequence.

The chopmark on this piece makes it a genuinely rare survivor, likely a unique specimin. Guatemala had little direct trade with China, but the coin could plausibly have moved through any number of intermediary hands, south through Pacific ports to Valparaiso or Callao, where it might have joined the broader flow of Latin American silver making its way westward into Chinese commerce.

Specifications:

Recorded mintage: 211,000
Catalog reference: KM A68

Details:
The 1856-S Seated Liberty half dollar, struck at the San Francisco Mint, is a product of the Gold Rush economy that transformed California after 1848. Silver coinage was in constant demand during this period, as gold dust dominated everyday transactions and reliable fractional silver was scarce. The San Francisco Mint, still relatively new in the mid-1850s, struck these halves to circulate locally in a fast-growing economy centered on mining camps, supply towns, and commercial hubs like Sacramento and San Francisco. As a result, many 1856-S halves saw hard use in frontier commerce, making them natural candidates for later alterations such as counterstamps.

sign
storefront

The counterstamp “J. L. POLHEMUS / DRUGGIST / SACRAMENTO CAL.” is attributed to James L. Polhemus, a well-documented Sacramento pharmacist active during the Gold Rush era. Like many Western merchants of the 1850s, Polhemus counterstamped circulating silver coins as a form of advertising and informal validation, ensuring his name traveled hand-to-hand with everyday money. In a fluid cash economy where private gold issues, worn federal coins, and foreign silver circulated side by side, counterstamping also signaled trust and local acceptance. Polhemus is known to have applied his stamp to half dollars and other silver coins, likely at his shop, turning both local and foreign coinage into a portable business card tied directly to Gold Rush–era Sacramento.

What makes this coin exceptional is the combination of a Gold Rush merchant counterstamp and a Chinese chopmark, linking two distinct monetary worlds on a single piece of silver. The most plausible path begins with the coin’s striking in San Francisco, followed by circulation inland to Sacramento, where it received the Polhemus counterstamp in local commerce. From there, the coin likely returned to San Francisco, the primary Pacific gateway for silver exports, before it was shipped across the Pacific to China, where it was tested and accepted by a Chinese shroff and marked with a chop. Few coins so clearly document the journey from gold rush California to China, making the coexistence of a Sacramento counterstamp and a Chinese chopmark a tangible record of California’s role between gold rush America and the global silver trade.

Catalog reference: KM Y28

Details:
In October 1897, Japan adopted an exclusively gold standard, revaluing the gold yen and effectively demonetizing the existing silver yen. For a six-month window, the public could exchange silver yen for gold, after which the remaining silver stocks were either melted for subsidiary coinage or shipped to Taiwan and other East Asian markets for use as bullion. To prevent these exported coins from being re-imported and presented for a second exchange into gold, the Japanese authorities applied a circular countermark containing the character 銀 (Gin, meaning "silver"). This mark served as a formal cancellation of the coin's legal tender status within Japan proper, while simultaneously certifying its metallurgical integrity for the regional trade markets.

The Gin countermark is traditionally found in a specific position relative to the 一 (Ichi, meaning "one") character on the reverse. While standard commercial chopmarks appear randomly across the coin's surfaces, the official countermark was applied with precision. According to some numismatic authorities, the Osaka Mint applied the mark to the left of the denomination, while the Tokyo Mint applied it to the right, though Japanese scholars remain cautious about this absolute distinction. This somewhat scarce with chopmarks in addition to the Gin mark; while the official countermark was intended to facilitate trade, the dual presence of an imperial stamp and a private shroff's mark represents a neat intersection of official Japanese monetary policy and the skeptical, decentralized verification system of the Chinese mainland.

According to some numismatic authorities, the Osaka Mint applied the mark to the left of the denomination, while the Tokyo Mint applied it to the right, though Japanese scholars remain cautious about this absolute distinction. This somewhat scarce with chopmarks in addition to the Gin mark; while the official countermark was intended to facilitate trade, the dual presence of an imperial stamp and a private shroff's mark represents a neat intersection of official Japanese monetary policy and the skeptical, decentralized verification system of the Chinese mainland.

This example is the scarcer "Type 1, No Border" variety.

Details:
Struck at the Madrid Mint, the "1870" Spain 2 Pesetas features a dual-dating system common to Spanish issues of the era; while the main legend displays the "1870" series date, the actual year of production, 1874, is incused in the small six-pointed stars on the reverse.

This example is modified with an integrated metal loop, a characteristic adaptation that allowed the coin to be suspended as part of a larger ritual assembly dedicated to localized deities. In this context, the coin’s physical presence served as a tangible expression of devotion, likely draped alongside other foreign silver issues around a ritual figure to invoke protection or good fortune. Most such ritual objects were eventually stripped of their value and returned to private hands as temple officials often reclaimed high-purity silver for reuse after the conclusion of ceremonies. See the 1806 US Half Dollar shown earlier for more information about these talisman offerings made with silver coins.

Recorded mintage: 2,726,000
Catalog reference: KM 377.10

Details:
This "BRYAN 1 1933" countermark (Brunk B-1237) is struck on an 1883 Mexico City 8 Reales host coin, also bearing several small Chinese chopmarks. This specific countermark is part of a series of political and economic tokens that reference the bimetallic advocacy of William Jennings Bryan. While Bryan’s primary influence peaked during his 1896 presidential campaign, where he championed the "free coinage" of silver to assist debtors and farmers against the constraints of the gold standard, this particular stamp belongs to a secondary period of silver agitation. The "1933" dating aligns with the silver speculation surrounding the Great Depression (1929–1939) and the issuance of "so-called dollars," such as the Pedley-Ryan pieces, as the public reacted to the United States' transition away from gold.

The presence of the countermark on this specific host coin documents a definitive three-country trajectory. The coin originated in Mexico at the Mexico City mint, struck to the traditional 8 Reales standard for international commerce. It then traveled via trans-Pacific trade routes to China, where it was accepted by local merchants and shroffs who applied small chopmarks to verify the silver's weight and fineness. Following significant circulation in China, the coin was transported to the United States. There, it was pulled from bullion or numismatic channels in the early 1930s to serve as a planchet for the Bryan political stamp, physically linking 19th-century global trade with a 20th-century American monetary populist movement.

The host coin is very common with chopmarks, though the application of the Bryan countermark significantly increases its rarity. The intersection of Chinese merchant marks and an American political stamp creates a unique historical record of a coin that facilitated trade in the Pearl River Delta before returning to the Americas to play a role in domestic silver speculation. The coin represents a physical confluence of the Mexican mining industry, western trade with China, and the American "Free Silver" debate.

1886-Zs JS Mexican 8 Reales with 1989 Freedom Dollar counterstamp

1886-Zs JS Mexican 8 Reales with 1989 Freedom Dollar counterstamp

Specifications:
27.07 g, .903 fine silver, .786 troy oz (actual silver weight)
Recorded mintage: 5,303,000
Catalog reference: KM 377.13

Details:
The 1886 Mexico 8 Reales, Zacatecas (Zs) mint, serves as the host for a large, politically significant counterstamp known as the "China Freedom Dollar." This mark features a central symbol of a crossed-out hammer and sickle, surrounded by the English legends "CHINA FREEDOM DOLLAR" and "SUPPORT THE FEDERATION SAVE THE STUDENTS." The opposing side of the stamp mirrors these sentiments in Chinese characters. These counterstamped pieces were issued in 1989 as part of a fundraising effort to assist members of the Berkeley Chinese Students & Scholars Association (B.C.S.S.A.) who were left stranded in the United States following the political upheaval in China.

The application of this counterstamp followed the Tiananmen Square protests and subsequent massacre (1989), an event that triggered widespread international condemnation and the formation of various support organizations for Chinese nationals abroad. By selecting silver coins that had historically circulated within China, such as the Mexican 8 Reales, the organizers created a physical medium that bridged 19th-century trade history with 20th-century political protest. This specific project utilized the coins as "freedom dollars," sold in commemorative envelopes to raise capital for students who could no longer safely return to their home country or access funds due to the turmoil in Beijing.

This type represents a unique intersection of two distinct periods of Chinese history, as a small proportion of the host coins used for the project bear authentic 19th-century Chinese chopmarks. The presence of these original shroff marks indicates that the type had traveled to the Chinese mainland during the Qing Dynasty, only to be repatriated to the West and eventually stamped with an anti-communist symbol a century later. The juxtaposition of the traditional mercantile chopmarks and the modern political counterstamp creates a layered narrative of China's shifting economic and social landscape. While the host coin is a common issue, the type appears to be somewhat scarce with chopmarks in conjunction with the 1989 stamp.

(1894) Guatemala Peso countermark on 1889 Peru Sol host (Ex. Murphy)

(1894) Guatemala Peso countermark on 1889 Peru Sol host (Ex. Murphy)

Specifications:
25.000 g, .900 fine silver, .7234 troy oz (actual silver weight)
Recorded mintage: Unknown
Catalog reference: KM 224

Details:
By 1894, Guatemala had undertaken a broader monetary reform, contracting the British firm The Mint, Birmingham, Limited to strike new domestic coinage and addressing the long-standing problem of foreign silver of varying fineness saturating the local market. A decree issued in July 1894 authorized the countermarking of foreign crown-sized silver at the Guatemalan mint, with the program beginning August 10 and running into early 1895. Coins meeting the required silver standard were brought in, tested, and struck with the obverse and reverse dies of the newly issued 1894 half real, applied within a peso collar that fixed the denomination. The result was a coin that carried Guatemalan imagery on both faces while preserving the host coin's design beneath.

The countermark itself uses the dies of the 1894 half real: the Guatemalan coat of arms on one side, and on the other the seated figure of Justice with the legend of the Republic, all within the larger peso collar that distinguished these pieces from the smaller denomination they referenced. The host coin here, an 1889 Lima sol, is one of the more common foreign silver types that circulated in Guatemala during this period, the Peruvian sol having tracked closely enough to Spanish colonial weight standards to remain trusted in Central American trade through the latter half of the nineteenth century.
