2 Pounds - Charles III Caernarfon Castle

Caernarfon Castle was the site of Charles's investiture as Prince of Wales in July 1969 — a ceremony watched by 500 million television viewers and staged by the Earl of Snowdon with considerable theatrical ambition, including a transparent perspex canopy that scandalized traditionalists. His accession to the throne in 2022 made commemoratives referencing that earlier title suddenly retrospective in character. The Isle of Man issues under Pobjoy Mint have long targeted this kind of biographical hinge point.
