For the first time in the history of the Britannia Series, the silver and gold bullion coins enter a new era with a portrait of King Charles III on the obverse. After a brief release of 2023 Britannias with Queen Elizabeth II’s portrait, the series moves forward with a bust of the king from Martin Jennings. Right now, 2023 1 oz British Gold Britannia Coins are available to purchase online from Certified Silver Reserve.
