1967 George Washington With Beard? Error?

What I am thinking is that this coin has been through a fire

Fire damage

Hey thanks everyone! :)
I am not completely sold on fire damage. My husband does demolition and deconstruction of old buildings. I have seen some fire damaged coins before, but none like this.
This coin was found in an unknown old building somewhere in Montana during a demo.
My reasoning is, when held it still has integrity and does not feel as though its been through high temps, its not thin or light.
The smear of beard area is thick and consistent. The shadows detract from being able to see this.
No signs of similar heating effects on the opposite side. Oh yea, the "We" as well as the "T" at the end of Trust are perfectly intact on top of the smear that I think looks like a beard.
Just my observations. What leads you to think fire damage?

also agree with the others, it's heat damage, not necessarily from structure fire, but probably a blow torch

Thanks all :)Heat damage it is.
