Britannia has a long-standing relationship with British coinage. The female embodiment of the nation may have ancient beginnings, first appearing on Roman coins circa AD 119, but she has evolved over time to reflect Britain’s strengths and values. The 2026 Britannia continues to define security in the bullion market as she appears on a coin that has four groundbreaking features. Surface animation creates a flowing wave effect in the background as the coin is moved. Between this and the banding of the coin, you will find micro-text 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. A latent feature in the lower left segment of the coin switches between a trident and a padlock based on the viewer’s perspective, which emphasises her naval strength and the coin’s safe nature. Tincture lines carefully highlight details such as the Union flag on Britannia’s shield and combined, the advanced features make it one of the most visually secure coins in the world.
