2½ Rupiah

This note belongs to a category of Indonesian Republican emergency issues produced at the residency level during the independence struggle — not by the central government in Jogjakarta, but by local administrative authorities scrambling to maintain a functioning money supply in territories cut off from reliable supply lines. Tandjungkarang, the administrative seat of the Lampung Residency in southern Sumatra, printed its own currency because it had to.

Locally produced issues from this period are notoriously variable in paper quality and print registration, a direct consequence of improvised production under wartime conditions. The 2½ denomination — the "two-and-a-half" unit common to Dutch colonial monetary convention — persisted in Republican issues largely out of habit and practical necessity for small transactions.
