Chaca, so you know how to calculate a coin's specific gravity but cannot tell that it does not look like a genuine Lincoln cent? Just find a good picture if you don't have an actual real wheat cent from the 1940s laying around somewhere to compare side by side.
Ok I went today another coin dealer and he told how much you want for it . I don’t think if it’s fake he will ask me how much you want for it. He looks the coin the number 3 he say it’s good . You know what I’m just I’m going to send it this week to get graded by Ngc .
