Britannia has embodied Britain and its people since the second century and just under two millenniums later, the icon is still instantly recognisable on a bullion coin. For 2025, our Britannia coin continues to lead security in the bullion market as the icon appears on a coin with four groundbreaking features. Surface animation in the background of Britannia reflects the flow of waves as the coin is moved and, between this and the banding of the coin, micro-text circles the design with the wording ‘DECUS ET TUTAMEN’, which translates as ‘an ornament and a safeguard’, and describes the features that both decorate and protect the coin. The lower left segment of the coin features a latent feature that switches between a design of a trident and a padlock based on the viewer’s perspective, emphasising Britannia’s maritime strength and the coin’s secure nature, whilst tincture lines highlight details such as the Union flag on Britannia’s shield. Combined, these enhanced security features along with Philip Nathan’s Britannia design form one of the most visually secure coins in the world.
