25 Rupiah Serang, Banten Residency

One of dozens of local emergency currencies issued across the Indonesian archipelago during the revolutionary period — when the newly proclaimed Republic faced a Dutch blockade, chronic paper shortages, and no functioning central bank capable of supplying remote residencies. Banten's administration printed its own scrip out of practical necessity, not monetary ambition.

These provincial issues were typically produced on whatever paper and equipment local government offices had on hand, which accounts for the wide variation in print quality seen across surviving examples. Banten had a reputation for fierce anti-colonial sentiment dating back to the 1888 revolt, and the residency was quick to assert its own administrative structures during the revolution.
