This is a pretty cool coin I have. I think it is a Neandrian Troas from the greek city state of Neandria. It features the head of Apollo facing right, and a horse grazing on the obverse. The letters NEAN are visible above the horse. A similar coin I found online is this one. I will show you the pictures of the coin, and the coin I found online. The first 2 are the ones I have, and the second two are the other one. If anyone has any more information about this coin, please tell me. Thanks everyone.
