heat, from lighter or blowtorch.

 

The surface is brillant on both sides without any heat signatures.

I doubt that it was caused by external heat.

 

Heat can do things that doesn't seem right----I'm not sure what did this---wait and see what Mike says...

It is probably an improper annealing error. Previously called "copper wash" and "sintered plating" errors, a thin layer of copper ends up at the surface of a coin exposed to heat that is too great or too prolonged.
