Thought this was interesting and maybe you guys would find it interesting. A relative of mine is a contractor and he was working on a house and found a 4x4 piece of steel in an attic crevice. The piece had an inverse reversed 1964 Jefferson nickel obverse on it with great detail in the date and mottos. My first thought was Francis Henning being that i'm from NJ and also because I have never heard of anyone else counterfeiting nickels. I took it and pressed a piece of lead into it with a C-clamp and was surprised how detailed the date and motto were, whereas Jefferson came out looking worn.
