Hi just like to show you this nice coin. It's a gold stater of the Corieltauvi tribe-North East Coast type. I found the coin a few years ago . I have recently sold the coin to a guy in California.
Celtic coins were not used like the Romans used coins. As they had no organised tax or monetary system. It was all barter/skill driven. 90% of the populus never had a coin.
Gold Coins were used at the highest levels by Chiefen's who used them in political persuasion. They were used by Druids for ritual purposes & to pay mercenary's their seasons pay. Also used to pay for great feasts which the Celtics enjoyed. Particularly the wine which they traded with the Romans, often swapping many captive slaves from other tribes to pay for it.
The gold was often melted down from Roman coins.
