The Board of Commissioners of Currency was a statutory body rather than a central bank — Singapore had no central bank at all until MAS assumed full currency functions, and even then the BCCS continued issuing notes independently until 2002. This note belongs to the Orchid series, the first family of purely Singaporean currency after the dissolution of the common Malaya and British Borneo currency arrangement in 1967.

Thomas De La Rue held the printing contract throughout the Orchid series run. The relatively short issue window for this denomination — two years — reflects the transition planning already underway toward the subsequent Bird series, introduced from 1976 onward in overlapping phases.
