Trinidad and Tobago gained independence in 1962 but retained British coinage designs for over a decade before the Central Bank introduced a fully localized series in 1976. The 1973 pieces fall within the transitional period when the newly independent republic was still issuing coins bearing the Commonwealth portrait while the bank finalized its own distinct currency identity. KM#58 was struck at the Royal Mint.
