That thing has so many problems, I don't even know where to begin.... First, it clearly has some environmental damage. The porosity of the coin is unusual. Second, it has obviously been polished. Third, it has been dipped or acid washed... probably to remove the environmental damage. That's what caused the weird twisted appearance of the devices. Fourth... after all that, someone put this poor thing into a plastic flip and now it has traces of PVC all over it. The green you seen covering both sides is PVC, and must be removed with acetone. This poor coin probably just needs to be flipped into a wishing well, and hope for better luck in its next life.
You know, with the wear, the polishing, the toning, and the PVC... I completely zonked on the possibility that it might be a fake. Wow. Got me.
I'm I wrong to think it may be a cast? The surface looks porous and the date numerals look like has extra metal.
Who Dat guy probably could have exposed that coin in a second........not me. Not my neck of the woods.
It isn't PVC damage. Whatever pot metal used to cast this atrocity, and whatever process it was put thru, typically yields the greenish look. I had a counterfeit large cent that turned from brown, to green, and then eventually to a sickish yellow over time.
Green to yellow......ghastly. @ Jason..........I'll get some of those toned cents up when I get back home. A day or two.
