2026 Great Britain 1 oz Gold Britannia Proof (w/Box & COA)
The 2026 Great Britain 1 oz Gold Britannia Proof coin represents a historic milestone in British numismatics, marking exactly 350 years since the female personification of the nation first graced circulating coinage. Struck in one troy ounce of 0.999 fine gold, this sovereign coin carries a face value of 100 Pounds and is backed by the British government. Its limited release of just 250 pieces makes it a highly exclusive artifact of modern minting artistry. The reverse of the coin features a design by Emily Damstra, which highlights Britannia's deep, historic connection to the surrounding sea. This side also displays the 2026 year of issue. On the obverse, the official effigy of King Charles III, created by Martin Jennings, is paired with the monetary denomination, surrounded by the traditional Latin inscriptions denoting his royal titles.
