500 Rupiah

Perum Peruri — Perusahaan Umum Percetakan Uang Republik Indonesia — had been printing Indonesia's banknotes domestically since 1971, ending the country's long reliance on foreign security printers. This 1988 500 Rupiah belongs to a period when the state-owned facility in Karawang was still consolidating its production standards, and quality consistency across print runs from this era can vary noticeably.

The watermark is the sole mechanical security feature, a relatively modest specification for a denomination that would have seen heavy daily use in late-1980s urban Indonesia.
