Launched in 2019, the Great Engravers Collection continues with a commemoration of Jean Baptiste Merlen’s reverse design for the 1831 crown. One of the rarest and most iconic designs in British numismatics, this modern interpretation has been re-mastered with the benefit of unique historical insight. It is also the first time Jean Baptiste Merlen’s work has featured in the Great Engravers Collection and commemorates an iconic design that is a masterpiece of engraving skill.

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 motif remained on the reverse side of the gold Sovereign until 1887. Celebrated for both its beauty and rarity, the 1831 crown holds a distinguished place in British numismatics. The William IV shield design features the Royal Mantle, with the Armorial Ensigns of the United Kingdom. The shield consists of the three lions of England, the rampant lion of Scotland and the harp of Ireland. As King William IV was the fifth sovereign of the House of Hanover to sit on the British throne, a small crown surmounted version of the Hanoverian Arms appears in the centre of the British shield. Surrounding the shield is the collar of the Order of the Garter. Shown under the crest, the text ANNO is seen to the lower left and the year 1831 is placed to the lower right.

Faithfully recreated using modern minting techniques, Jean Baptiste Merlen’s crest of King William IV is featured on the reverse and centred. Below the primary design is the commemorative inscription INSIGNIA GULIELMI IV BRITANNIAE REGIS. The obverse side includes the effigy of HM King Charles III created by sculptor Martin Jennings. The denomination from 5 to 5000 POUNDS and year of issue of 2026 also appears on the obverse as part of the legend surrounding the King’s likeness.
