I need some help on this one, a recent purchase. The silver coin came with only the tag, Greek Coin, Island of Kios. There is no inscription on the obverse, just what appears to be a male head. On the reverse is some kind of strange design and the three letters KIO- S with the sigma separated from the kappa iota omicron. The weight of the coin is 9.7 grams, which does not seem to fit any weight system I am familiar with. Perhaps a di-drachma or stater? Any help on figuring out just what this coin is and its approximate date is much appreciated.
Macedonia, Skione, but it doesnt look right to me. Probably fake, but the issues as a whole tend to look weird so it might be best to have it looked at by Sear or someone else in person.
You are definitely right about it being from Skione but I can only find tetradrachmas of ca. 16.9 to 17.0 grams listed and tetrobols of about 2.3. grams. A 9.7 gram coin just does not fit into the system used in Macedonia at that time (Fifth Century BC).
