10 Rupiah Oeang Republik Indonesia Daerah ORIDA

ORIDA — Oeang Republik Indonesia Daerah — notes were emergency regional currencies authorized by the central government in Jakarta after it became clear that the Dutch naval blockade was strangling the distribution of nationally printed money. Sumatra issued its own series rather than go without a functioning medium of exchange during the independence struggle. These were not rogue emissions; they had official sanction, but production quality and paper stock varied considerably depending on what was available locally at the time of printing.

The S190 series exists in multiple signature and paper varieties, with the "c" suffix distinguishing a specific combination that collectors treat as scarcer than the base type. Dutch military pressure during the 1947–1948 Agresi Militer operations disrupted distribution across much of the island, meaning many notes never reached circulation at all.
