50 Cents - Elizabeth II

Trinidad and Tobago gained independence in 1962 but retained British colonial coinage until a full decimal currency system was introduced in 1964, when the Central Bank issued its first domestic series. This 50-cent type debuted with that reform and continued through the mid-1970s largely unchanged — a period when the country's economy was being transformed by the first oil shock of 1973, which turned Trinidad into one of the Caribbean's wealthiest states almost overnight.

The window of 1973–1976 captures exactly that transitional moment before petroleum revenues prompted a broader rethinking of the currency's design vocabulary.
