The 2023 1oz Gold Britannia Bullion Coin is struck by The Royal Mint as part of the United Kingdom's flagship Gold Britannia bullion series. It contains one troy ounce of fine gold and belongs to the modern fine-gold Gold Britannia era, a long-running programme that links British legal tender coinage with international bullion collecting.
The obverse features King Charles III (Martin Jennings effigy), while the reverse carries Standing Britannia with advanced security features. The Britannia figure, first introduced to the modern bullion series in 1987 through Philip Nathan's celebrated design, gives the coin a strong British identity and makes the series instantly recognisable among world bullion issues.
For collectors, the 2023 issue forms part of a date run that charts the development of the Gold Britannia from its 22-carat origins through to modern 999.9 fine gold and advanced-security releases. It remains a popular annual bullion coin for those collecting by year, monarch portrait or major design period. This 2023 King Charles III issue is a major modern transition coin, representing the first Gold Britannia bullion release to carry the new Martin Jennings portrait of King Charles III.
