Browse our range of British Britannia 5p Silver 1/40oz Coins, struck by The Royal Mint in fine silver (.999 in modern issues). These ultra-fractional Silver Britannia coins represent one of the smallest and most specialist denominations in the Britannia series, highly sought after by collectors due to their limited mintages, intricate detail, and inclusion in official Royal Mint proof sets.

Each coin contains 1/40 troy ounce (approximately 0.78 grams) of pure silver and carries a 5p face value. While the denomination is symbolic, the true value of these coins is driven by their proof quality, extreme scarcity, Royal Mint craftsmanship, and strong collector demand.

The Silver Britannia series was first introduced in 1997 and has become one of the most iconic modern British coin programmes. The 1/40oz 5p format has been issued in select years as part of Royal Mint collector proof sets, making it significantly rarer than standard bullion and even other fractional denominations.

Each coin features the iconic Britannia design, symbolising strength, integrity, and British maritime heritage. Modern issues incorporate advanced Royal Mint security features such as radial lines, micro-text, latent imagery, and surface animation, making Britannia one of the most advanced and secure coin designs in the world.

This category includes British 5p 1/40oz Silver Britannia coins, including:

  • Annual Britannia 5p proof coins (select years, 1/40oz format)
  • Queen Elizabeth II issues across multiple portrait eras
  • Modern 999 fine silver fractional releases (select years)
  • Certified PCGS and NGC graded fractional Britannias
  • Extremely limited Royal Mint collector issues
  • Proof set fractional components (1/40oz format)
  • Special commemorative and anniversary releases

Fractional Britannia coins in the 1/40oz format are among the rarest issues in the entire Britannia series, typically only available within full Royal Mint proof sets. Their extremely small size and limited availability make them highly desirable for advanced collectors completing full Britannia date runs.

Whether you are building a complete Britannia proof collection or searching for ultra-rare fractional silver issues, this category represents one of the most specialist areas of modern Royal Mint numismatics.
