10 Dollars

Trinidad and Tobago's large-denomination circulation coinage of the early 1980s was issued against a backdrop of the country's oil boom beginning to soften — petroleum revenues that had funded ambitious public spending through the 1970s were contracting sharply by 1983. The Central Bank had only been issuing its own notes and coins independently since 1964, and the $10 coin represented an unusually high face value for a circulation piece in the anglophone Caribbean at the time.

KM#55 is part of a short-lived series that saw little sustained use as circulating tender.
