1700s (This thread in world coins). Most are copper and a few might be billon. This one looks like it might be a little older than the others--the style looks Medieval to me. I see a central cross with dots in between the arms and a ring of dots circling it. 17 mm diameter, 0.74 grams Any suggestions as to what country it might be from or what might be a good way to start trying to identify it? It's a bit worn to tell much, but I'd love to satisfy my curiosity. Cost of the whole lot came out to about 70 cents per coin, so I don't have much to lose! Thanks for any suggestions.
