William IV Gold Two Pounds Coin

Coins from the reign of William IV (1830–1837) are highly significant due to their brief production window and the high artistic quality of the 1831 Coronation Proof Set. Because silver crowns were only struck as proofs and never for general circulation, they are among the most coveted rarities in British numismatics.
