2 Pounds - Charles III Castle Rushen

Castle Rushen, the subject of this issue, is one of the best-preserved medieval castles in the British Isles — a limestone fortress in Castletown that served as the seat of the Lords of Mann and, later, as a prison. The Isle of Man has long used its coinage to document Manx heritage that Westminster has no incentive to commemorate, a consequence of the island's status as a Crown Dependency outside the United Kingdom's legislative reach.

Charles III coinage from the Isle of Man entered circulation following his accession in September 2022, with the Manx government moving independently of the Royal Mint's production timeline.
