100 Roepiah/Rupiah

One of the more unusual issuing arrangements in Indonesian monetary history: the Sumatran provincial government printed and circulated its own currency during 1947 while the revolutionary Republic was simultaneously fighting Dutch military action under the first "Police Action" that began in July of that year. Pematangsiantar, a highland town in North Sumatra, served as a de facto administrative center during this period precisely because it was inland and harder to hold under Dutch pressure.

The Propinsi Soematera notes were not a rival currency — they were an expedient, filling a vacuum left by disrupted supply lines from Yogyakarta. Provincial issues like this were gradually withdrawn as central Republican authority reasserted itself after 1949.
