U.S.-PHILIPPINE CURRENCY
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.
Role in Philippine Currency History
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.
Historical Significance
U.S.–Philippine coinage marked the transition from a fragmented colonial currency system to a standardized monetary system, stabilizing the Philippine economy under American administration while reflecting both U.S. sovereignty and emerging Filipino identity.
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. 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.
Architect of the Monetary Reform
The reform was largely based on recommendations by economist Charles A. Conant, who proposed a currency system aligned with U.S. monetary policy while suited to the Philippine economy.
Denominations Introduced in 1903
The Philippine Coinage Act introduced a new series of coins denominated in pesos and centavos. The smaller denominations were intended for everyday commerce, while the silver coins served as the primary circulating currency for larger transactions.
Bronze Coinage
½ centavo, 1 centavo
Copper-Nickel Coinage
5 centavos
Silver Coinage
10 centavos, 20 centavos, 50 centavos, 1 peso
Later Commonwealth Range
1 centavo to 50 centavos
The ½ centavo ("Kusing") was later discontinued, and the 1 peso also ceased as a regular denomination before the Commonwealth series. In 1907, silver coins were revised to reduced size, weight, and silver content, and later changes also affected the 5 centavos. These changes reflected the evolving monetary needs of the period.
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 feature a seated Filipino figure holding a hammer beside an anvil, with a volcano in the background. The silver denominations display a standing female figure holding a hammer resting on an anvil, with the same volcanic landscape in the background.
The reverse design also reflected the political status of the Philippines. Early issues featured the seal of the United States. During the Commonwealth period beginning in 1937, the reverse was modified to display the coat of arms of the Commonwealth of the Philippines.

Figure Attribution in Design
Numismatic sources suggest that the standing female figure may have been modeled after Figueroa’s daughter.
Minting of U.S.-Philippine Coins
Early U.S.–Philippine coins were struck at United States mints. In 1920, the Manila Mint was reopened to produce coins locally for circulation within the Philippines. 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.
Commonwealth Coinage (1937–1945)
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 the Series
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.

Summary
U.S.–Philippine coinage played a central role in the monetary history of the American colonial era. It replaced a mixed and unstable currency environment with a standardized decimal system, reflected both American sovereignty and Filipino identity in its design, and continued through the Commonwealth period until the disruptions of World War II and the transition to full independence.
