I own many coins thought to be from Kolone. There are a variety of both
obverse and
reverse styles which distinguish these coins from others. Neither the
obverse nor the
reverse of this coin looks exactly like any of mine. I realize this post is old, I was searching for Kolone and it popped up. The differences in
style in Kolone coins to me show a progression which indicates that if these were all struck in the same city, they were done so over a lengthy period of time. There also seems to be a difference in
weights which makes me think there are a couple of
denominations here. I do not have it all catalogued and written down, so I cannot provide to you the sort of
quality details that would be of more use. But I would say this. There appears to be a progression from a semi archaic representation of
Athena to, eventually, a more defined
Athena with more of a "chiseled" jaw and sharper features. This
Athena in your photo is most similar to the Kolone coins I view as the more recent issues. And even then, it seems a little different
still. This has become one of the only coins I collect anymore.
