1 Rupiah 'Sudirman' issue

Percetakan Kebayoran was Indonesia's primary domestic security printer through the 1950s and 1960s, and its output was technically modest by international standards — adequate for small denominations but rarely distinguished. This 1 Rupiah belongs to a period when Bank Indonesia was printing fractional notes largely because coin shortages made small-change transactions impossible in daily commerce.

General Sudirman, who commanded Indonesian forces during the 1945–1949 independence struggle while suffering advanced tuberculosis, appeared on several low-denomination notes of this period. Dying in 1950, he became the revolution's most potent military symbol precisely because he never held political office.
