Looks like might be ANTΩNINOC in the obverse legend, and I can believe that 1:00 - 3:00 might be ΔIAΔOV of ΔIAΔOVMENIANOC, as on some AE's of Diadumenian from Anazarbus, Cilicia. For a comparison to some obverses from Anazarbus, although with different reverses than yours, here's an AE29 at left, AE 31 to the right. OP at top.

Another, AE30:

The above coins have reverses different than the OP coin. However, here's a reverse, perhaps similar to the OP's, from another Anazarbus issue (once again, it's a Diadumenian). But the obverse legend is different on this one:

No definitive match for the obverse/reverse combo, above. But perhaps a point in the right direction?
