10 000 Dollars

The Board of Commissioners of Currency, Malaya and British Borneo was a joint currency authority created in 1952 to issue a unified currency across Malaya, Singapore, North Borneo, Sarawak, and Brunei — an unusual colonial monetary arrangement that outlasted most of its member territories' time under British administration. This $10,000 note is the highest denomination in the 1953 series, intended strictly for interbank settlement and large commercial transfers rather than retail use.

Surviving examples are genuinely rare. At that denomination, notes were typically cancelled and destroyed once cleared, leaving very few intact specimens in private hands.
