I was at a jeweler's and he mentioned that he had an ancient coin. He showed me this: anyone know anything about it?
Flattening on the reverse rim suggests the item was removed from a mount. I suspect it was a replica made to be used in jewelry since the style just does not strike me as familiar. I could be shown to be wrong.
I find it peculiar that the reverse seems "dirty" compared to the obverse. Regardless of whether it is genuine or fake it resembles a Corinth silver drachm with Aphrodite and Pegasus. I concur with Doug that the obverse die design is unfamiliar and strikes me as not being authentic.
Here is a Corinth Drachm from my little collection: CORINTHIA, Corinth AR Drachm Late 4th Century B.C. 2.6 grams, 14.5 mm Obv: Pegasos flying left, koppa below Rev: Head of Aphrodite left, hair in a sakkos, delta in front, iota behind. Grade: gF toned Other: Older references identify the head as Nymph Peirene. Corinth mint. From Bedford Coins May 2013
Diana was a Roman goddess equated with the Greek Artemis. I still believe the item is modern so it is not all that easy to ID from a style that really does not match anything I've seen. Artemis has a tendency (not always) to be shown with a bit of her quiver behind the head. That is a sure tip off. Just looking at the face, I might have considered Arathusa, Aphrodite, Demeter or Persephone first but anything is possible. Below are two Greek coins with quivered Artemis for comparison.
Thanks for the replies. I'm starting to agree with Doug that it is modern. The bust just seems to look that way.
