Like many other mints, the Royal Mint issues bullion coins in precious metals, having much higher intrinsic value than their face value. The five ounce (5 oz) silver coins are denominated as ten pounds (£10).
The coins are legal tender but are not intended for circulation. They are targeted at bullion investors or collectors who appreciate the special editions as pieces of art. The coins are typically "one-year" types usually issued in parallel with smaller denominations with the same reverse designs.
Britannia coins belong to an extensive range of British bullion coins issued by the Royal Mint in gold since 1987 and in silver since 1997. The range has a "definitive" Standing Britannia design issued every year as bullion (such as this coin), and a series of one-year types issued as collector proofs only.
The five ounces of silver format was added to the Britannia range in 2025.
The Royal Mint says about the coin:
For centuries, Britannia has embodied the female personification of Britain, evolving over time to reflect the nation's spirit and identity. Her origins trace back to the 2nd century, appearing on the coins of Roman Emperor Hadrian. Since 1672, Britannia has been a constant presence on British coinage. Today, she graces The Royal Mint’s flagship Britannia bullion coin. This globally recognised portrayal, crafted by sculptor Philip Nathan in 1987, symbolises Britain's essence with carefully chosen elements: a shield for protection, an olive branch for peace, and a trident to represent maritime power. Only The Royal Mint is authorised to produce authentic Britannia coins featuring Nathan’s award-winning design, with the 2025-dated bullion coins continuing this proud tradition. |
