In 2020, to celebrate Britain's Longest Reigning King George III, the Royal Mint released a Limited Issue George III £5 Five Pound Gold Proof Coin struck in solid 22 Carat Gold.
The reverse designed by Dominique Evans features a portrait of King George III while the obverse depicts the Fifth Portrait of Her Majesty Queen Elizabeth II both designed by Jody Clark. These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
