The Negros Emergency Currency Board was one of several provincial authorities that issued guerrilla currency in the Philippines after the Japanese occupation disrupted normal banking. These notes were produced locally under wartime conditions — Negros Occidental maintained enough organizational cohesion to sustain a functioning, if improvised, monetary system through much of the occupation, backed loosely by the promise of post-liberation redemption by the Commonwealth government.

Alfred J. Montelibano was a prominent Negrense sugar planter and political figure, his name lending the currency a degree of local credibility that purely bureaucratic signatures could not.

S679 notes are relatively scarcer than lower denominations in the series, consistent with typical guerrilla issue patterns where high-value notes were printed in smaller quantities.
