25 Pounds - Elizabeth II 2006 FIFA World Cup

Guernsey has no meaningful connection to football and no FIFA membership — this is frankly a bullion-adjacent commemorative issued purely to capture collector demand around the 2006 Germany tournament. The island's authorities have issued dozens of such topical gold pieces since the 1990s, leveraging Crown Dependency status to produce legal tender coins with no expectation of circulation.

The .9166 fineness is standard 22-karat, the same alloy used in sovereign coinage since 1817.
