I know nothing at all about these kind of coins. All I know is it is a Celtic coin and nothing else except what the seller described. I have never read anything about Celtic coins but this one just stood out to me. I probably paid to much but oh well, I like it whatever it is. $54 shipped Sellers description A Celtic Gaul potin coin of Senones. From around the 1st Century BC. Cast. Obverse shows warrior's head right; reverse shows horse left. Diameter approx 17mm, weight approx 4.61g.
