I will try it, but when I was super zoomed in on the edge of the raised material it looked exactly like it had a wave around it that dips downward then straight up like one piece of metal. Like if the metal got sucked from it, but I thought when that happens you see traces on the other side. It's also gots that copper green look, that copper gets when it has chemical reaction of oxidation. I can definitely see it being a possibility for a foreign object to be stuck on it, but I did pick at it with a wooden pick since I wood shouldn't hurt copper if I it is, and it the wooden pick broke without leaving any mark. I was thinking it was possibly an error with the combing of different metals for the planchet and got compromised during the heating process, but I'm still learning. Cheers!
