Theres is a bubble right in front of his face, just a little bump of raised metal, but it also is in the same spot on the reverse side of the coin.. Any thoughts??? i have some knowledge of error coins but not much.

If one side is concave and the other convex, I'd be inclined to say damaged by a BB or pellet shot.

 

both sides have a bubble ,,, as if someone took a BB cut it in half an welded it to both sides, in the same place in the front as in the reverse.. best example i can give lol

 

I strangle believe it is from extreme heat exposure. Ive seen this on more common coins such as state quarters.

 

I agree with vdbpenny , this coin has probably been in a house fire or some other fire. I have found a few coins in the ashes from house fires and this is what some of them looked like.

 

i mean to me, it doesnt show any evidence of heating. There isnt any errors like this that could occur in minting?

 

no there are not any errors like this that could possibly occur during the minting process to put a round bump on both sides of the coin directly opposite each other. high heat is about the only thing I know of that can do this to a silver coin. I see what looks like hundreds of pin head size bumps on your coin , this would also confirm it has been really hot , also the color of the silver is right for the coin to have been really hot.

 

It's possible that something damaged both dies but in that condition the coin is worth melt.

 

It is indeed from heat. Just seen a quarter in hand a few months ago. I think Potter wrote an article about it in the Errorsope or there is one coming on it.
