1 Crown - Elizabeth II Platinum Wedding Anniversary

Tristan da Cunha issues commemoratives through the British Crown dependency mechanism, with coins produced by the Pobjoy Mint or similar contractors rather than any facility on the island itself — the archipelago has no mint and a permanent population of roughly 250 people. The platinum wedding anniversary (70 years) of Elizabeth II and Prince Philip in 2017 generated a wave of licensed issues across British overseas territories, of which this is one.

Tristan da Cunha has no indigenous currency circulation; these pieces are legal tender in name only.
