The iconic Britannia has represented Britain, and the country’s evolution, since Roman times. She is a symbol of the nation at a point in time. In 2021, Britannia leads the way once more, redefining security in the bullion market with four groundbreaking features. This new vision of Philip Nathan’s Britannia, created in 1987, was created by the team behind ‘the world’s most secure coin’, the United Kingdom £1 coin. Surface animation provides a background for Britannia, reflecting the flow of waves as the coin is moved. Between this and the banding of the coin you will find micro-text with the wording – DECUS ET TUTAMEN, or AN ORNAMENT AND A SAFEGUARD, describing the features that both decorate and protect the coin. A latent feature in the lower 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. Finally, details like the Union Flag on Britannia’s shield have been specially highlighted with tincture lines. These landmark design elements combine to create not only a stunning Britannia, struck in half an ounce of 999.9 fine gold, but also the most visually secure coin in the world.

These features are also available on the 1oz, 1/4oz and 1/10oz fine gold editions of the coin, and on the 1oz fine silver edition.
