500 Riels

The 500 Riel occupies an awkward commercial position in Cambodia — by 2014 the denomination was worth roughly twelve US cents, and the country's heavy dollarization meant it functioned primarily as change-making currency rather than a meaningful store of value. The National Bank has maintained the series partly to assert the riel's presence in everyday transactions, where USD coinage is absent and small riel notes fill the gap.

P#66 continues a long-running design family for this denomination, with security specifications modest by regional standards — a basic watermark and thread, no color-shifting ink or microprinting.
