1 Crown - Elizabeth II Royal Wedding - Prince Charles

Issued a decade after the 1981 wedding it commemorates, this piece belongs to a wave of retrospective royal issues that flooded the market in the early 1990s as Commonwealth territories sought low-cost commemorative revenue. The Turks and Caicos Islands — a British Overseas Territory with no central bank and the U.S. dollar as its de facto currency — had limited practical use for crown-sized copper-nickel pieces, which circulated nowhere and were sold directly to collectors.
