2026 William IV 1831 Crown One Kilogram Gold Proof Great Engravers Coin
One kilo William IV Crown gold proof coin, from a limited edition of just five pieces. Struck in an extraordinary 1,000 grams of 999 fine gold, this monumental 2026 issue from The Royal Mint presents Jean Baptiste Merlen's celebrated 1831 Crown reverse on its most impressive scale within the Great Engravers series. The 10-centimetre canvas reveals the full splendour of Merlen's Royal Arms, encircled by the Order of the Garter and framed by a draping ermine mantle. This design never saw circulation, and surviving examples from the reign of King William IV remain very rare and highly sought after. Faithfully remastered with modern minting precision and finished to the highest proof standard, this exclusive 24-carat gold one-kilogram coin is a tribute to The Royal Mint's long tradition of outstanding craftsmanship.
