5 Centavos

Negros Oriental was one of several Philippine provinces that issued its own emergency guerrilla currency after the Japanese occupation disrupted the supply of central bank notes. These provincial issues were authorized locally and printed under improvised conditions — paper stock, ink quality, and print registration vary considerably across surviving examples of the Negros Oriental series.

The S651 designation places this firmly in the wartime emergency scrip category documented by Pick. Bacolod, the provincial capital of Negros Occidental rather than Oriental, appears anomalously in the issuer line — a detail worth scrutinizing against the physical note, as attribution errors in this series are not uncommon in the literature.
