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 the nation’s strengths and values. The 2023 Britannia continues to define security in the bullion market as she appears on a coin that has four groundbreaking features. Surface animation provides a background for Britannia, reflecting the flow of waves as the coin is moved, and 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-hand segment of the coin switches between a trident and a padlock based on the viewer’s perspective – emphasising her maritime strength and the coin’s secure nature – and details such as the Union flag on Britannia’s shield have been specially highlighted with tincture lines. The advanced features have been combined to create a stunning Britannia design that is also the most visually secure coin in the world. 

The coin is also available as a tenth-ounce fine platinum edition. There are also various gold and silver editions of this coin, which include four advanced security features.
