Pisidia, Antioch. See if you can make out some of the obverse legend. The portraits are not "true", so these Pisidian coins from Gallienus, Valerian, Philip I, Volusian, etc tend to look similar. I think yours is Valerian but you're in a better position to read the letters with the coin in hand. http://www.cngcoins.com/Coin.aspx?CoinID=102137 162, Lot: 200. Estimate $75. Sold for $45.
