I've had this coin for over 15 years but I just recently started to flesh out the numismatic specifics. I've gone around in circles since yesterday afternoon with it. If you, or someone you know, can put me out of my misery, I'd be hugely appreciative! It is surely safe to presume it's a coin on which Damnatio Memoriae was exacted. And because of the evidence of it being a dual portrait obverse coupled to a reverse showing a horse-and-rider (presumably Zeus Panamaros), the logical presumptions would be that (a) the obverse's removed portrait is/was Geta, (b) the obverse's remaining portrait is Caracalla, and (c) the host coin is SNG von Aulock 2682, 2685, or 2689-91. (All those types were issued in Stratonicaea in Caria, under Septimius Severus, have a Caracalla / Geta dual obverse portrait, and a Zeus Panamaros on horseback reverse.) BUT... not only is the 31.5 mm. diameter slightly small for any of those options, but under the horse's forelegs I see a kneeling captive facing right, not a lighted altar as is the norm for the SNGvA cites listed above. For a Thracian Caracalla reverse with a very similarly shaped and positioned captive see: https://www.acsearch.info/search.html?id=4800768 I have begun to wonder if the host coin's obverse could be a Caracalla and Julia Domna dual portrait, since some of those sub-types do include a captive under the horse. However... that would mean that in antiquity someone mistakenly defaced/removed Julia Domna instead of Geta. Further complicating an attribution, the worn and purposely obliterated obverse left no obverse legend to aid any attribution. 31.5 mm. 15.25 g. In addition to seeking a host coin attribution, I'd love to have a Howgego c/m number. I have Howgego's book, but have been unable to find a match. Howgego 188, 536, & 233 are the three c/m's I found associated with Geta's Damnatio coins, but none of those seem to be a match. Below are 2 different close-up images of the countermark. (I rotated each one 90-degrees to the left because it looks like it goes that way. I think I see a head with eyes and hair, and a torso underneath -- possibly with wings?) Note also that it looks like someone tried to remove the horseman's head also, which would be a little odd. Thanks for reading this far!
