1 Sovereign - Elizabeth II Platinum Jubilee - Queen on throne

Alderney has used its status as a Crown Dependency to issue commemorative sovereigns since the 1990s, sidestepping the Royal Mint's monopoly on standard British sovereigns while retaining legal tender status within the Bailiwick of Guernsey. The Platinum Jubilee in 2022 marked Elizabeth II's 70th year on the throne — the longest reign of any British monarch and the only British sovereign to reach that milestone.

She died on 8 September 2022, roughly eight months after this coin's issue date.
