1oz Gold Britannia Coins

Discover our collection of 1oz Gold Britannia bullion coins from The Royal Mint — the flagship denomination in Britain’s most recognised modern gold bullion series. First introduced in 1987, the £100 Gold Britannia has become one of the world’s leading investment gold coins, combining iconic British design, trusted Royal Mint quality, and worldwide bullion recognition. Each 1oz Britannia contains one troy ounce of fine gold and remains highly sought after by both investors and collectors for its liquidity, security, and enduring appeal.

Featuring the timeless image of Britannia — the enduring symbol of Britain’s strength, resilience, and maritime heritage — 1oz Gold Britannia coins have evolved through multiple portrait and reverse design variations across the series. Early issues from 1987 to 2012 were struck in 22 carat gold (.9167 fine), while all modern Britannias from 2013 onwards are produced in .9999 fine gold, helping establish the series as one of the world’s premier pure gold bullion coin programmes.

This category includes a wide range of 1oz Gold Britannia coins, including:

• £100 Gold Britannia bullion coins
• Queen Elizabeth II Britannias
• King Charles III Britannias
• Modern .9999 fine gold Britannias
• Earlier 22 carat Britannias
• Brilliant Uncirculated bullion issues

Modern 1oz Gold Britannias incorporate advanced anti-counterfeit security technology introduced by The Royal Mint in 2021, including surface animation, latent image technology, tincture lines, and micro-text. These features have helped make Britannia one of the most visually secure bullion coin series in the world while maintaining its status as a trusted investment-grade gold coin.

Popular releases within the series include first-year 1987 Britannias, the 2013 transition to .9999 fine gold, the 2021 security-feature Britannias, final Queen Elizabeth II issues, and the first King Charles III Britannias introduced from 2023 onwards. Many investors build long-term gold holdings using 1oz Britannias due to their global recognition and UK Capital Gains Tax exempt status, while collectors often assemble complete date runs and portrait collections across the full Britannia series.
