It is currently thought the Celts brought coins to what is currently known as the United Kingdom in about 150 BC.
The first coins made in Britain were gold coins struck by the Celts in or around 70 BC. Prior to that, there were imported coins circulating, dating back to about 150 BC.
The first coins to circulate in Britain date to around 150 BC and were brought from Northern Gaul by the Celts. The coins were made from gold and known as a "Stater". The Celts began minting gold "Stater" and "Quarter Stater" coins around 100 BC and smaller silver and bronze denominations known as a "Unit" and fractional coins in each metal.
It was the 2nd century BC.
