Browse our selection of British Britannia £1 Gold Proof Coins, struck by The Royal Mint in one-twentieth of a troy ounce of 999.9 fine gold. These fractional Britannia coins form part of the internationally recognised Britannia series, combining historic British symbolism with investment-grade gold in a highly accessible format.

The Britannia series is one of the world’s most established gold bullion programmes, first introduced in 1987 and now struck in 24-carat gold. The £1 Britannia gold coin represents one of the smallest and most affordable denominations in the range, making it an attractive entry point for collectors seeking official Royal Mint gold coins.

Each coin carries a face value of £1 and is legal tender in the United Kingdom. Despite their small size, these coins feature the same iconic Britannia design and advanced security features as larger denominations, including micro-text, latent imagery, surface animation, and radial line detailing.

This category includes a range of Britannia £1 1/20oz gold coins, including:

  • 1/20oz Britannia gold proof coins
  • Certified PCGS and NGC graded Britannia coins
  • Limited mintage Royal Mint releases
  • Special edition and presentation issues
  • Modern King Charles III Britannia coins

Britannia £1 gold coins are highly sought after due to their affordability, collectability, and Royal Mint prestige. They are also exempt from UK Capital Gains Tax, making them an appealing choice for both new collectors and experienced numismatists looking to diversify into fractional gold.

Whether you are starting a gold collection, adding fractional Britannia coins to an existing portfolio, or searching for specific Royal Mint proof issues, this category offers one of the most accessible ways to own official British gold.
