These crownsized patinas were made to show what coins of William IV might look like, if they had ever been struck. You have the bust of William IV on the obverse, just like on the 1831 crown by the Royal Mint. In fact, some would argue, it is as good, or better, than the original. The reverse faithfully reproduces the crown of 1826. They are retro-dated 1836. These are full crownsized and Prooflike – handsome and beautiful coins. They were minted in various metals, such as pewter, copper, brass, cupro-nickel, aluminium and bronzed copper.  Mintages were low and so these are very collectable.
