Browse our range of British Britannia 10p Silver 1/20oz Coins, struck by The Royal Mint in 999 fine silver. These ultra-fractional Silver Britannia coins were issued exclusively from 2013 onwards as part of modern Royal Mint collector proof sets, making them one of the rarest and most limited denominations in the entire Britannia series.

Each coin contains 1/20 troy ounce (approximately 1.55 grams) of pure silver and carries a 10p 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.

Unlike earlier fractional Britannia issues, the 1/20oz format was introduced only in the modern Britannia series from 2013 onwards, following the standardisation of Britannia silver coinage to 999 fine silver. These coins were issued in extremely limited quantities and are typically only available as part of full Royal Mint proof sets.

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

This category includes British 10p 1/20oz Silver Britannia coins(2013–present), including:

  • Modern Britannia proof coins (2013 onwards, 1/20oz format)
  • Queen Elizabeth II later portrait issues
  • King Charles III Britannia releases (where applicable)
  • 999 fine silver fractional proof coins
  • Graded PCGS and NGC Graded fractional Britannias

The 1/20oz Silver Britannia is one of the smallest and most exclusive denominations in the modern Britannia series.

Whether you are building a complete modern Britannia proof collection or searching for ultra-fractional Royal Mint issues, this category represents one of the most specialist and limited areas of contemporary British coinage.
