1 Peso Green seal, different border

The Negros Emergency Currency Board was one of several provincial Filipino authorities that issued guerrilla currency during the Japanese occupation, operating under the tacit authorization of the Philippine Commonwealth government-in-exile. These notes circulated in Negros Occidental as a practical alternative to the Japanese-issued Mickey Mouse money, which locals refused or discounted heavily. The "different border" designation in the Pick catalog distinguishes this variety from the more common border type — a distinction that matters for completeness but rarely affects collector demand dramatically.

Paper quality and ink consistency vary considerably across the 1944 guerrilla issues, a direct consequence of wartime supply constraints.
