Ok I just got back from a jeweler's shop and he tested the three in front of me and the result was that the three are made of gold..Just as I thought I had no doubt about that ever. The only doubt I had was regarding their authenticity because it peaked recently which pushed me to post them here on this great site. Anyways, the jeweler said that two(the roman ones) are 20K gold and the Greek one was close to 22K gold and the gold in that coin is much better quality then in the other two.
Thank you all again...Thank you DV for this suggestion, actually I thought of doing just that with the coin I still had it's receipt and go resell it to the same jeweler's shop I bought it from so if somebody wanna buy it again he'll see the inscription that it's fake and won't buy it but then I thought since this guy work with gold he can just erase that and resell it again and screw somebody else, that ain't gonna happen. Another thing, even if they are fakes it's not easy getting rid of them because they've been with you for so long for sooo many years you know.
