I found a 2006 Nickle that has no back to it. Now I don't mean a back that was rubbed flat or not printed. This has no "core" I guess you can say. It looks like something fell out of it and it only has the front and the ring with an indented back and what looks like glue residue.
Is this possible? Are the coin solid or in fact pieced together?
From my view the front looks like a real coin but I'm not an expert
