The Potin denomination
Potins are Celtic coins cast in bronze with up to 25% tin content, as well as substantial lead content. Potins were cast in all of Gaul, roughly modern-day France and Belgium, as well as some tribes in Britain.

Potins often look fairly crude and worn, but they are often in 'as cast' condition. They all but disappeared after the Roman conquest, when they were replaced by Roman coinage.
