200 Pounds - Charles III John Lennon, Gold Proof

This coin is part of the Royal Mint's ongoing Beatles series, marking the 45th anniversary of Lennon's death in December 1980. The .9999 fineness — four-nines gold — is notably purer than the traditional .9167 used for British sovereigns and most earlier Royal Mint bullion, a specification the Mint has increasingly adopted for prestige collector issues over the past decade.
