1 Dollar - Hassanal Bolkiah 25 Years - Currency Board

Brunei's Currency Board was established in 1967 following the dissolution of the Board of Commissioners of Currency Malaya and British Borneo, giving the sultanate independent monetary administration for the first time. This 1992 gold issue marks twenty-five years of that institution — not Hassanal Bolkiah's reign, which is a distinction the catalog title blurs. The Sultan ascended in 1967 as well, so the anniversaries coincide, but the coin is formally a Currency Board commemorative.

Brunei and Singapore maintained — and still maintain — a Currency Interchangeability Agreement dating to 1967, under which their dollars trade at par.
