Here's what I know. My friend has had this coin for some thirteen years. He obtained it from his daddy-o. Dad reportedly got it in Iran about fifty years ago from someone who said he dug it up. Friend and dad apparently thought or assumed it was gold. I do not think it is gold. I think it is copper; it smells like copper to me. Here are the stats - it weighs 3.60 grams and has a diameter of 23.50 millimeters. My tests for density come to 9.2308, which tells me something with loads of copper (or nickel?) - and maybe something else. Any help or suggestions will be immensely appreciated. I don't know if it is authentic. Perhaps a contemporaneous counterfeit? The lettering to me (not experienced with this type and also not the sharpest knife in the drawer) seems less than hardy (bland, not very sharp). But what do I know? I presume it was hammered but still; my hammered medieval Europeans have a better appearance. I'll be glad to provide any data I failed to mention, if I know it.
