10 Dollars - Elizabeth II Royal Wedding

The East Caribbean Currency Authority issued this piece to mark the July 1981 marriage of Prince Charles and Lady Diana Spencer — one of several dozen Commonwealth and associated territories that produced commemorative coinage for the event. The ECCA served eight small island states collectively, meaning a single minting decision applied across all of them simultaneously, with no individual territory able to opt out or vary the design.

Copper-nickel at this size and weight mirrors the Pobjoy Mint formula used for dozens of similar Commonwealth commemoratives that year, making the 1981 royal wedding one of the most heavily commemorated single events in 20th-century numismatic history by sheer issuer count.
