History of Britannia

Lady Britannia made her first appearance on Roman coins in AD 119 during the Roman era under the rule of Emperor Hadrian but disappeared after the collapse of the Roman Empire. She reappeared during the reign of King Charles II, and Britannia has since featured on every subsequent British monarch.

Obverse

The obverse of the coin features the uncrowned portrait of King Charles III by Martin Jennings.
