25 Pounds - Elizabeth II Peter Rabbit, Gold Proof

Issued to mark the 150th anniversary of Beatrix Potter's birth, this was part of the Royal Mint's first-ever Potter-themed coinage — a licensing arrangement that proved so commercially successful it spawned multiple annual releases and became one of the Mint's strongest performing collector series of the decade. The proof version was struck in four-nines fine gold, a purity standard the Royal Mint had only adopted for its bullion Britannia series in 2013.
