Just a guess.
<< <i>Looks like some kind of heat damage. Perhaps something very hot fall across the face of the coin and melted the copper plating into the zinc core, forming an area of brass Its raised, and stamped into the coin, image even shows up in it, so I would think it fell on the planchet, before it got struck >>

Zinc melts way before copper. If both melted there would be no design left and it would be deformed.
And dropped elements are struck into not raised
Are you sure it's not a foreign substance like glue?
It was probably a temp test melting a eutectic strip.
<< <i>It can't be a dropped element since there is no element of that size and shape to drop

Upon seeing the new picture I think you are right. Looks like glue atop the surface.

I will try acetone, I never used it, so the internet will be my resources, on how to use with copper cents, still has some nice color under that black stuff, which I think is dried grease, but the gold object is not going away, its some kind of metal object, maybe brass ..
Acetone generally won't bother the copper nor toning. I suspect those who have experienced color change with copper and acetone probably had some thin film of something on the coin beforehand.
Acetone is flammable and you just soak away from an ignition source.
