The language on this coin is Greek, not Latin - the giveaways are the "W"-shaped omegas - Latin doesn't have a letter W.
Back when happyprince first posted this coin, he was posting a whole bunch of interesting and rarely encountered Greek and Roman Provincial bronzes from the area around what is now northwestern Turkey. Most we (or the folks over on FORVM, where he posted as well) could roughly identify, this one we couldn't.
The reverse doesn't have much readable text, except for "AVT" (or perhaps DVT). On the obverse, you can read quite a lot of the lettering around the portrait: "...TWN K....A?ALEWN...". But entering this (and any reasonable alternative interpretation of it) into the
Wildwinds partial inscription search came up empty.
My best guess, now I've had a few months to think about it: Tabala (TABALEWN}, in Lydia, western Turkey.
This one is very similar, and has an obverse legend that fits (IEROPOLITWN KAC TABALEWN), but the whole coin is not similar enough to inspire any certainty in this attribution.
Coins from this part of the world just don't come onto the market often enough to get a good representation of these coins on the online databases. You need the specialist catalogues, which I don't have.
