Here's another dot AΓ (ligate) and pentagram hemidrachm in a Forvm member gallery. I think it's a reverse die match of my coin-- and maybe to yours. Do ours match? I think they might. http://www.forumancientcoins.com/gallery/displayimage.php?pos=-13833 I bought mine on eBay near the beginning of my ancients collecting. I would not do that again . I did check various databases prior to buying, but since then I've seen enough fakes to make me wary of the type.
The Forvm coin matches neither of ours, though the reverse die of yours might be a match to mine. I can't tell with certainty. The three obverses are all different.
I agree that the obverses are all different. After playing around with the reverses in Photoshop (adjusting rotations, overlaying the reverses with varying degrees of transparency for the top coin), I believe all three are indeed the same reverse die. I'm still not entirely confident of my coin's authenticity and am not sure if this information helps or hurts . Forvm coin / TypeCoin971793 coin / TIF coin The overlays. It's easier to see when doing the overlays "live", moving the transparency slider in real time.
