The British two pound (£2) coin of the pound sterling. Its obverse has featured the profile of Queen Elizabeth II since the coin’s introduction. Three different portraits of the Queen have been used, with the current design by Jody Clark being introduced in 2015.

In February 2015, the Royal Mint announced a new design featuring Britannia by Antony Dufort replacing the previous design. The new coins feature the edge inscription 'QUATUOR MARIA VINDICO', meaning "I claim the four seas", an inscription previously featured on coins bearing the image of Britannia.

Britannia is the national personification of Britain as a helmeted female warrior holding a trident and shield. An image first used in classical antiquity, the Latin 'Britannia' was the name variously applied to the British Isles, Great Britain, and the Roman province of Britain during the Roman Empire. Typically depicted reclining or seated with spear and shield since appearing thus on Roman coins of the 2nd century AD, the classical national allegory was revived in the early modern period.
