This is not a heated coin. I don't know what it is but as Silviosi says, the heat needed to wrinkle the copper plating would destroy the plating. And it would be black. It's just a few shades difference than a common cent. Maybe the planchet didn't get plated right, zinc rot started in the inside but not breaking any of the skin. Rot has to go somewhere so it buckled the plating.

At one time it was normal. Other wise the devices would not all be there. It was altered. How? The color changes on the coin indicate heat to me.

By the reflex of your photos, I will conclude was put on heat. I do not think at a torch, I am more versus an induction stove. Your coin took a heat above 200 deg and less then 700 deg C.
