<p>[QUOTE="Conder101, post: 1300292, member: 66"]Interesting. Rare piece, rare certificate. The only thing I wonder about is how would you test such a piece to determine what it is? By appearance it would look like a regular copper nickel or nickel planchet. Of course since it is a sandwich type material you might be able to determine that the outer layers are not magnetic but the core is. Of course that would be true for coppernickel clad steel as well. But coppernickel clad steel would have a lower specific gravity. Does it have any of the paperwork from INS saying what tests were done?[/QUOTE]</p><p><br /></p>
