Images of Britannia show her sitting or lying down with a spear and shield. This image was first used on Roman coins in the 2nd century AD. After the Romans, the image of Britannia was first used again for coins of the pound sterling made for Charles II of England, Scotland, and Ireland. These were the first to show Britannia with a Union Flag on her shield. After many victories of Britain's Royal Navy, coins with Britannia show Neptune's trident from 1797. Her image wears a helmet on coins after 1825.
