10 Pounds - Charles III Royal Arms, 10 oz Fine Silver

The Royal Arms design used here derives from the heraldic achievement granted to the sovereign, which differs from the version used by the British government — a distinction that trips up collectors more often than it should. Charles III's accession in September 2022 prompted a full revision of all Royal Mint coinage, making the earliest issues of this reign transitional pieces in a program that won't be fully replaced across circulation and bullion series for several years.
