Certified Britannia Coins

Explore our extensive collection of Certified Britannia coins from The Royal Mint — a premium selection of authenticated and professionally graded Britannia issues spanning gold, silver, and platinum. Featuring proof, bullion, and brilliant uncirculated (BU) finishes, this category showcases some of the most desirable modern British coins, all certified and graded by leading third-party services such as PCGS and NGC for authenticity, condition, and collectability.

Britannia coins are one of The Royal Mint’s flagship series, first introduced in gold in 1987, followed by silver in 1997 and platinum in 2018. Since then, the range has developed into a full multi-metal investment and collector series, featuring annually changing designs, royal portrait transitions, and advanced security features on modern issues. Today, Britannias are struck in gold (.9999 fine), silver (.999 fine), and platinum (.9995 fine), making them among the most internationally recognised modern bullion and numismatic coins.

Bullion and BU issues remain highly liquid investment coins, while certified graded examples offer additional assurance of condition, preservation, and long-term collectability.

Modern Britannias also feature advanced Royal Mint security enhancements, including surface animation, latent image technology, tincture lines, and micro-text, making them among the most secure bullion coins in the world.
