1/2 Crown - Elizabeth II Sovereign

Tristan da Cunha, a British Overseas Territory in the South Atlantic with a permanent population under 300, issues coins primarily for the collector market — it has no functioning retail economy that circulates them. This 2008 piece is part of a broader sovereign-format series that exploits the island's issuing authority while targeting bullion and numismatic buyers rather than islanders.

At 0.5 g of .9999 gold, the actual metal content is negligible by bullion standards — roughly a third the weight of a 1/25 oz piece.
