U.S.-Philippine Coinage (1903-1946)
U.S.–Philippine coinage—often referred to by collectors as USPI coins—comprises the series of coins issued for circulation in the Philippines during the period of American administration from 1903 to 1946. Introduced under the Philippine Coinage Act of 1903, this monetary system established a Philippine peso tied to the United States dollar while maintaining denominations familiar to the Philippine economy.
These coins formed the foundation of the Philippine monetary system throughout the American colonial era. Early issues were struck at United States mints, and beginning in 1920, production also took place at the Manila Mint, the only United States branch mint ever established outside the continental United States, located in Manila.
Today, U.S.–Philippine coins remain an important part of Philippine numismatic history and are widely collected for their historical significance, distinctive designs, and their connection to both American and Philippine monetary systems.
The series includes the well-known U.S.–Philippine peso and centavo denominations, widely studied by collectors of both Philippine and United States territorial coinage.

Historical Background
At the beginning of the 20th century, the Philippines lacked a unified and stable monetary system. During the final decades of Spanish rule and the early years of American administration, a wide variety of coins circulated throughout the archipelago. These included Spanish colonial coins, Mexican pesos, and other foreign silver coinage commonly used in regional trade.
The coexistence of multiple currencies created significant challenges for commerce and government administration. Exchange rates fluctuated, and the absence of a standardized system complicated taxation, trade, and financial management.
To address these issues, American authorities sought to introduce a modern monetary system specifically designed for the Philippine economy.
The Philippine Coinage Act of 1903
The foundation of the new monetary system was established through the Philippine Coinage Act of 1903, enacted by the United States Congress. The reform was largely based on recommendations by economist Charles A. Conant, who proposed a currency system suited to the economic conditions of the Philippines while remaining aligned with U.S. monetary policy.
Under the new system, the Philippine peso was pegged at two pesos to one U.S. dollar, creating a stable exchange rate based on a gold exchange standard. Although the Philippine coins themselves were primarily struck in silver, their value was supported by reserves tied to gold through the U.S. monetary system.
This reform introduced a standardized decimal coinage system for the Philippines, replacing the diverse mixture of foreign coins previously in circulation.
Denominations Introduced in 1903
The Philippine Coinage Act introduced a new series of coins denominated in pesos and centavos.
Bronze Coinage
-
½ centavo
-
1 centavo
Copper-Nickel Coinage
-
5 centavos
Silver Coinage
-
10 centavos
-
20 centavos
-
50 centavos
-
1 peso
The smaller denominations were intended for everyday commerce, while the silver coins served as the primary circulating currency for larger transactions.
Design of U.S.–Philippine Coins
The distinctive designs of the U.S.–Philippine coinage were created by Filipino sculptor Melecio Figueroa, incorporating symbolic elements representing both the Philippines and the authority of the United States. The designs were selected through a design competition organized by the Philippine Commission in the early years of American administration.
Two variations of the obverse design were used across the series. The bronze and copper-nickel denominations—such as the ½ centavo, 1 centavo, and 5 centavos—feature a seated Filipino figure holding a hammer beside an anvil, symbolizing labor and industry, with a volcano in the background, commonly identified as Mayon Volcano in Albay, one of the most recognizable elements of U.S.–Philippine coin design. The familiar inscription "FILIPINAS," first seen on the Spanish decimal coinage, appears prominently.
The silver denominations—including the 10, 20, and 50 centavos and the 1 peso—display a different obverse design depicting a standing female figure holding a hammer resting on an anvil, with the same volcanic landscape in the background. Numismatic sources often suggest that the figure may have been modeled after the daughter of Figueroa.
The reverse design remained largely consistent across the series. Early issues featured the seal of the United States, reflecting American sovereignty over the Philippines. During the Commonwealth period beginning in 1937, the reverse was modified to display the coat of arms of the Commonwealth of the Philippines.

Minting of U.S.–Philippine Coins
Early U.S.–Philippine coins were struck at several United States mints, including:
-
Philadelphia Mint
-
San Francisco Mint
-
Denver Mint
In 1920, the Manila Mint was reopened to produce coins locally for circulation within the Philippines. Originally established during the Spanish colonial period, the facility became the only United States branch mint ever located outside the continental United States.
During the 1920s and 1930s, the Manila Mint produced large quantities of U.S.–Philippine coins for local circulation, helping reduce reliance on shipments from American mints.
Coin production in Manila continued until the outbreak of World War II, when the mint was destroyed during the Japanese invasion of the Philippines in 1941.
For a more detailed history of the Manila Mint, including its construction, operation, and role in Philippine monetary reform, see our blog post: "The Manila Mint: A Turning Point in the Philippines’ Monetary History."
Commonwealth Coinage (1937–1944)
A significant change in the design of U.S.–Philippine coinage occurred during the Commonwealth period. When the Philippines became a Commonwealth of the United States in 1935, new coin designs were introduced beginning in 1937.
The reverse of the coins was modified to feature the coat of arms of the Commonwealth of the Philippines, replacing the earlier U.S. seal used on previous issues. Despite this change, the inscription “United States of America” remained on the coins to reflect the political relationship between the two governments.
These Commonwealth issues continued to circulate until the disruption caused by World War II.

World War II and the End of U.S.–Philippine Coinage
The U.S.–Philippine coinage system came to an abrupt halt during the Japanese invasion of the Philippines in 1941. The Manila Mint was destroyed during the conflict, and the established currency system was replaced by Japanese occupation currency.
After the war, the Philippines eventually introduced its own national coinage following the country’s independence in 1946, marking the end of the U.S.–Philippine coin series.
