OK. This little guy has me stumped. It is a 6mm, 0.24g AR coin. It has the odd hook on it. I was thinking this was a Lesbos boar fractional type- the ones with the weird curl or possibly a head of a goat. Single incuse on the rev. Any help is appreciated.
I don't think it's Lesbos, at least not the Koinon mint with boar fractions. I don't know if you have any, but those ones are billon and don't usually look much like full silver in hand (and tend to be much "lumpier" fabric). There are lots of weird Asia Minor (and Thrace) Hemiobols and Tetartemoria like this that are still unidentified, could be one of those (I have a bunch). Kinda looks like a dolphin?
Well, Thasos is out. One of my good colleagues is a Thasos expert and says "Nope." I think I found here. But the odd thing is that CNG doesn't actually have a listing for 159..it kinda disappeared..there is a lot 158 and 160. Strange.
That's because it went unsold. They don't include them on their website archive if unsold. Which is terribly frustrating from the standpoint of research. I encounter this constantly with their archive.
