5 Pesos

Negros Occidental was one of several Philippine provinces that issued its own emergency currency after the Japanese occupation severed normal banking operations in late 1941 and early 1942. These provincial guerrilla notes — sometimes called "guerrilla pesos" or "emergency notes" — were authorized under the Commonwealth government's emergency powers and circulated alongside, and in direct competition with, Japanese-issued military pesos, which local populations increasingly distrusted.

The province's notes were printed under difficult conditions with limited materials, and paper quality varied considerably across printings. Counterfeiting of emergency issues was a documented problem throughout the Visayas region during the occupation years.
