I have been buying some war nickels. I have five that are very shiny and look new. Actually they don't even look new, the new ones have a different type of shine to them. Hard to explain. Three of these nickels are 43s and two are 45s. The 45s do not have the same mints, two of the 43s have the same mints. They look incredibly similar. I don't have a scale but I guess that is the deciding factor.
I will try to post pics later. Anybody know if there are fakes floating around? These came from ebay, but not all from the same seller. I think 4 did though.
