Can you all help me. I have an 1871 Amadeo I 5 pesetas coin that looks like it is a proof coin. Did they make any proof 1871 coins
In the stars either side of the date is 18-71 and the makers mark S.D. Can anyone tell me anything about this and how I can authenticate it or not.
On the edge is written something like Liberty with some starts then some other word. Any help would be appreciated.
