I know there are two types of this 1943 Franc without the mint mark. There is a light weight one, and a heavy version. The heavy version is more valuable and in demand than the light weight one. So beside identifying it on weight alone, is there a way to tell if I have the rare version? Sorry for the quality of the pictures. I'm taking it to a PCGS authorized coin dealer tomorrow, and I'm hoping he will have a gram scale and I can get the answer for which one I have.
