Mountain Province was one of several Philippine administrative regions that issued emergency guerrilla currency after the Japanese occupation disrupted normal banking in early 1942. The Provincial Board had no printing infrastructure to speak of, and these notes were produced under genuinely improvised conditions — locally sourced paper, hand-stamped or rudimentarily typeset, with serial numbering often applied inconsistently across the series.

The S-prefix in the Pick reference denotes Philippine emergency and guerrilla issues catalogued separately from the central series. S602 is among the rarer provincial entries; Mountain Province's remote terrain isolated it from both Japanese administration and Allied resupply, which affected how broadly these notes actually circulated before the liberation.
