1 Crown - Elizabeth II Jubilee Monarch

Tristan da Cunha, the most remote permanently inhabited island on earth, has no meaningful domestic coin circulation — the nearest bank is roughly 2,400 kilometers away in Saint Helena. Crowns issued under its name are struck by the Pobjoy Mint or similar contractors for the collector market exclusively, with the island's British Overseas Territory status providing just enough legal standing to issue currency that will never change hands at a shop.

The 2012 Diamond Jubilee prompted a flood of commemorative issues across Commonwealth territories. Gold-plated copper-nickel at this weight places it firmly in the souvenir tier rather than the numismatic one.
