1 Crown - Elizabeth II Royal Marines - Gold Plated

Tristan da Cunha, a British Overseas Territory in the South Atlantic with a permanent population under 300, issues commemorative coinage through licensing arrangements rather than any domestic minting infrastructure. The Royal Marines connection here ties loosely to the island's administrative history — the garrison that briefly occupied the island in the Napoleonic era eventually gave rise to the permanent settlement that exists today.

Gold-plated copper-nickel crowns of this type were produced in large numbers across multiple British territory licensees during the 2010s, often sharing dies across different issuing authorities.
