The Negros Emergency Currency Board was one of several provincial emergency authorities that began issuing guerrilla currency in the Philippines after the Japanese occupation disrupted legitimate banking. Negros Occidental had a functioning resistance administration, and these notes were produced to pay local suppliers, soldiers, and civilian workers — not as symbolic gestures but as working money used in a genuine shadow economy operating under occupation.

The S662 is among the more commonly encountered Negros guerrilla issues, though significant condition variation exists. Notes that circulated heavily often show fold damage along the center horizontal, a characteristic of how they were carried folded in pockets during wartime.
