5 Pesos

Guiuan sits at the southeastern tip of Samar, and in 1943 it was under Japanese occupation. This note is one of the guerrilla or municipal emergency issues produced across the Philippine provinces during that period, when the Japanese-issued Mickey Mouse peso had collapsed public trust and local authorities improvised their own scrip to keep markets functioning.

Samar's wartime issues are among the less-documented of the Philippine guerrilla currencies — survival rates vary sharply by municipality, and smaller coastal towns like Guiuan produced limited quantities that rarely made it into major collections.
