500 Riels

P#14 spans a notably long issue window — from the late 1950s through the final years before the Khmer Republic replaced the Banque Nationale du Cambodge in 1972. The Banque de France produced the series using its standard intaglio process, and the quality of the printing held consistent across the run, which complicates precise dating of individual notes without examining signature combinations.

Signature variants on this series correspond to successive governors and finance ministers, and attributing a specific note to its sub-period depends entirely on those pairings. At least three distinct signature combinations are documented across the issue years.
