1 Crown - Elizabeth II 90th Birthday - Silver

Tristan da Cunha sits roughly 2,400 kilometers from the nearest landmass and has fewer than 300 permanent inhabitants — the most remote permanently settled territory on earth. Its commemorative coinage is produced entirely for the collector market; no meaningful circulation occurs. The island's numismatic program is administered through the British Crown Dependencies framework, with coins struck under license by private mints and marketed internationally.

Elizabeth II's 90th birthday generated a considerable volume of issues across British Overseas Territories in 2016, making individual territorial strikes largely interchangeable as collectibles.
