1 Peso

The Philippine Commonwealth Treasury Certificate series of 1941 was authorized under the Commonwealth Government's effort to establish a distinct Philippine currency framework ahead of planned independence, scheduled for 1946. This 1 Peso note was among the last printed before the Japanese invasion of December 1941 effectively ended normal monetary administration. Large quantities of Commonwealth-era notes were deliberately destroyed by retreating American and Filipino forces to prevent enemy use — a policy carried out with enough thoroughness that survival rates for circulated examples from this series are lower than the print run alone would suggest.

The Bureau of Engraving and Printing produced these in Washington, the same facility handling U.S. federal currency at the time.
