10 Rupiah

Djambi — now spelled Jambi — was a residency on the east coast of Sumatra, and like several other Indonesian residencies in the immediate post-independence period, it issued its own emergency paper money when central supply of currency collapsed under the chaos of the Dutch military actions and the ongoing independence struggle. These residency notes were provisional instruments, authorized locally and circulated within tight geographic boundaries.

Pick 266 is among the more obscure of the Sumatran residency issues. Documentation on exact print runs is thin, and surviving examples are genuinely rare — not because the notes were well-preserved, but because wartime circulation in tropical conditions was brutal on paper currency.
