5 Pounds - Elizabeth II Caernarfon Castle

Struck to mark the 30th anniversary of the investiture of Prince Charles as Prince of Wales at Caernarfon Castle in July 1969 — a ceremony choreographed largely by the Earl of Snowdon and broadcast live to 500 million television viewers. Guernsey, alongside Jersey and the Isle of Man, became a reliable source of commemorative silver issues throughout the 1990s, producing pieces tied to British royal events despite having no constitutional obligation to do so.

KM#75 is one of several Guernsey issues from this period sharing the same 28.28g sterling blank used across Commonwealth commemorative programs.
