William IV 1831 Crown 2026 UK 2oz Silver Proof Coin

The Coin Company is proud to present the William IV 1831 Crown 2026 UK 2oz Silver Proof Coin produced by The Royal Mint.                       

The Royal Mint’s Great Engravers Collection continues with a commemoration of Jean Baptiste Merlen’s reverse design for the 1831 crown.

Jean Baptiste Merlen (1769–1850) began his career at the Paris Mint but left France soon after the Battle of Waterloo. In 1820, William Wellesley Pole recruited him to work with The Royal Mint and assist Benedetto Pistrucci in preparing the coinage for the new king, George IV.

Best known for his reverse designs, including those for the 1820 half-crown and the Maundy Money designs from 1822, Merlen was a skilful engraver and although he retired in 1844, his shield motifs remained on The Sovereign until 1887.

Celebrated for both its beauty and rarity, the 1831 crown holds a distinguished place in British numismatics. Now, the design has been faithfully recreated using modern techniques and brought to life on the reverse of this new 2026-dated coin.
