Apayao was one of several Mountain Province sub-provinces that issued emergency guerrilla currency during the Japanese occupation of the Philippines. These provincial notes were authorized under wartime necessity, not by any central banking authority, and their legitimacy depended entirely on local administrative continuity and public trust in whoever was still running the civil government from the hills.

The S-prefix in the Pick reference places this firmly in the Philippine emergency issues — a category where survival rates vary wildly by issuing locality. Apayao's remoteness in northern Luzon likely worked in its favor during the occupation, but against widespread circulation.
