The 2025 silver Britannia 1oz coin, containing 31.1 grams of fine silver at a purity of 999 parts per thousand. It is sourced directly from the Royal Mint's refinery in Llantrisant, Wales and is sure to continue to be a favourite choice for silver investors For more than 1,100 years, The Royal Mint has combined tradition and innovation to create beautiful, secure and trusted coins. In 2025, Britannia continues to lead the way in defining security in the bullion market. This latest incarnation of the icon combines Philip Nathan’s 1987 interpretation with four pioneering security features to create one of the most visually secure coins in the world. These additions have been applied to both decorate the coin and make it secure, just as the micro-text that borders the design states – ‘DECUS ET TUTAMEN’, which translates as ‘an ornament and a safeguard’. In the lower part of the design, below Britannia’s flowing gown, a trident represents the icon’s maritime history. As the viewer changes their perspective of the coin, the trident turns into a padlock that emphasises the coin’s secure nature. Surface animation reflects and represents the movement of waves behind Britannia and tincture lines highlight fine details such as the Union flag on Britannia’s shield.
