cyrrhus, is this coin ok?...it looks a bit strange to me. a bit "soft" on the details? kind of looks like a seam as well. hope i'm wrong.
http://www.cngcoins.com/Coin.aspx?CoinID=227591 MESOPOTAMIA, Edessa. Macrinus. AD 217-218. AR Tetradrachm. Laureate, draped, and cuirassed bust right / Eagle standing facing, head right, with wings spread, holding wreath in beak; shrine between legs. Prieur 863 Coin is OK too, not a fake, just porous.
coin is perfect got around 100 syrian Tets, this one is so nice because it is not the same thickness overall, just a silver metal slab hit by a hammer, so rough but good.
