20 Riels

Bradbury Wilkinson printed this note for the Banque Nationale du Cambodge during one of the more turbulent stretches of Cambodian monetary history — the issuing window spans from independence-era optimism through the Lon Nol coup of 1970 and into the early years of the Khmer Republic. The same plate served across that entire range, which means physically identical notes circulated under radically different political administrations.

The long issue span makes precise dating nearly impossible without accompanying signatures or serial prefixes. Bradbury Wilkinson's New Malden facility handled a significant share of Southeast Asian currency work during this period, and Cambodia was among their steadier clients before the banking system collapsed entirely in 1975.
