2 1/2 Rupiah

The Bukittinggi issues of 1947 are among the more administratively peculiar notes from Indonesia's independence period. When the Dutch reimposed control over Batavia and Java following the August 1945 proclamation, the Republican government relocated key functions to Sumatra — Bukittinggi in West Sumatra became a provisional capital of sorts, and local currency printing followed from sheer necessity rather than any centralized monetary plan.

These regional emergency notes were produced under improvised conditions and are frequently found with uneven ink coverage and rough-cut margins, which is a feature of production rather than post-issue damage. The 2½ denomination itself reflects the Dutch colonial reckoning still embedded in Indonesian monetary arithmetic at the time.
