If a coin is smooth on one side, is it a coin. medal, or a commemorative? I have such a thing and need help. On the non-blank side is a 3D image of Napoleon facing left. Dated 1769 and 1969. "bicentenaire de la naissance de l'empire" or "bicentenary of the birth of the empire" So if I had a camera I could send an image. I think it is pewter. Is it a coin medal, commemorative, or something else? Anyone know anything more about this enigma? Regards, King_George_Va
