2 Pounds - Elizabeth II Queen Mother

Tristan da Cunha issues coins primarily through the British Crown's authorization, with pieces like this effectively functioning as collectibles rather than circulating currency — the island's economy runs largely on stamps and fishing licenses. The Queen Mother commemorative series from this period was produced by the Pobjoy Mint, which held a long-running contract for numerous British Dependent Territory issues throughout the 1980s and 1990s.

Elizabeth Bowes-Lyon turned 90 in 1990, the occasion this piece marks.
