I'm thinking this is intentional damage of some sort. No idea what or why, but I don't know of any roll crimper that could have done this. The metal displacement and patterns are very interesting too! Almost looks as if the copper alloy became very hot during the process. I'd put it in a 2X2 and save it just because it's different!
