The smallest platinum coin in the range Struck in one-tenth of an ounce of 999.5 platinum  Features Philip Nathan’s award-winning Britannia design  Includes four advanced security features Encapsulated in protective blister packaging  The 2025 Britannia coin range masterfully combines tradition and innovation, celebrating the enduring symbol of Britannia while showcasing cutting-edge security features. The coin’s flowing wave effect, achieved through surface animation, adds dynamic depth. At the same time, micro-text bearing the Latin phrase “DECUS ET TUTAMEN” (an ornament and a safeguard) highlights its protective and decorative nature. A latent feature switches between a trident and a padlock depending on the angle of view, symbolising Britannia’s naval strength and the coin’s secure nature. Additionally, tincture lines meticulously enhance details such as the Union flag on Britannia’s shield, creating one of the most visually secure and technically advanced coins ever produced.
