5 Centavos

Negros Occidental was one of several Philippine provinces that issued emergency guerrilla currency after Japanese forces occupied the islands following the fall of Corregidor in May 1942. The Provincial Currency Board notes were authorized under emergency powers and produced locally with whatever materials and equipment were available — Nalco Press was a commercial operation pressed into wartime service, not a security printer.

The series circulated alongside similar issues from other provinces, each effectively operating its own monetary system. American military authorities later redeemed many guerrilla notes after liberation, but redemption records for the Negros Occidental series are incomplete.
