My opinion this was done with a torch.

I dont think so ... to bubble out the reverse side it would have to be hot enough to 'hole' the obverse side.

 

Something trapped BETWEEN layers / metal mixture 'lumpy'

Edge looks clean

 

Dunno

It's certainly grotesque, and most assuredly not a mint error.

I think that the used the torch on the edge of the coin breifly which cause the buble on both side......plus I think I can see where they used the torch becuase their is some white chalky residue

The odd color on part of the reverse make me think heat was used to do this.

Maybe a grill or something. I don't know.

 

Someone posted this question to the auction.

If you want to change your auction description for this coin it's called a lamination error and yes it happened at the mint.

That is strange but I would think that a torch causes too much heat to be able to cause this without really damaging any other part of the coin!

the pimple on the coin needs to lanced with a white hot iron
