Found this coin in a lot I just recently purchased. Looks to be Spanish. Has what appears to be solder, shape is con-caved like a button. Any ideas what it might be?
i believe it is a castle on one side and i lion on another, that's a common theme with old spanish coins.
Philippus III the king of Spain. Tell me the size and I tell you the face value. Now I can say that it's 2-, 4-, or 8 maravedis only. Something like this.
It's a 4 maravedis. I added a link above. Minted coin at 3.29 grams and 18mm. A worn flattened coin could easily go to 3g and 20mm.
