50 Cents

Singapore's first decimal coinage series launched in 1967, the same year the city-state's currency formally split from the common Malaya and British Borneo dollar that had circulated across the region since 1953. The Monetary Authority of Singapore did not yet exist at issue — these early coins were struck under the Board of Commissioners of Currency, Singapore, which predated the MAS by four years.

The series ran through 1985 before being replaced by a lighter, smaller coinage. Royal Mint (London) and the Singapore Mint both handled production across the run.
