  • The iconic Britannia coin design features four advanced security features

  • Packaged in tubes inside a durable box 

Created by the team behind the United Kingdom’s 12-sided £1 coin, which is known as ‘the world’s most secure coin’, the Britannia 2025 bullion coin features innovative security technology that make it the most visually secure bullion coin in the world. 

Struck in 999.9 fine gold and enhanced with four security features, Philip Nathan’s depiction of Britannia is as beautiful as ever on this bullion coin. In the lower left of the design, below Britannia’s flowing gown, a trident represents her naval history and as the viewer changes their perspective this trident becomes a padlock, emphasising the coin’s secure nature. Surface animation reflects the movement of waves and fine details such as the Union flag on Britannia’s shield have been carefully highlighted in the coin’s bullion finish. These added security features both decorate and protect the coin, just as the micro-text that borders the design states – DECUS ET TUTAMEN’, which translates as ‘an ornament and a safeguard’.
