50 Pence - Charles III Queen Elizabeth II Centenary

Queen Elizabeth II was born on 21 April 1926, making 2026 the centenary of her birth — though she died in September 2022, four years before the milestone. Guernsey has a particular connection to the late monarch: the island issued its first distinct decimal coinage in 1971 and has consistently used the occasion of royal anniversaries to produce commemorative pieces outside the standard circulating series. The partial gold plating on this issue follows a finishing technique Guernsey's minting partners have applied to several recent commemoratives to distinguish them from circulation strikes.
