1976 D Jefferson Nickel Error

I'd just spend it. The condition of the coin would probably not be desirable at any price more than face.

I'm interested in seeing this area after you give it a good acetone bath. It's probably glue or some type of adhesive.

just a beat up, damaged nickel

Ok sorry I needed research how to go about the acetone bath. I have been carful to remove as much dirt as possible without causing more damage even if it's not worth a thing but face value, I am still interested to know if this is possibly something that can happen to the coin say if tape or plastic was stuck on there years ago then let's say something such as cola was spilt onto and left in an area where no one removed ether or items for a few years I would like to know if it a would eat it away at the compound of the coin. If not what's the best way to determine if the coin was damaged during the mint processing and then later it's environment in some senerio caused damageing to the coin in other ways.I think I worded the follow-up question with the information I am seeking If not then let me know so I can try to clarify the details. On other note I have carefully trued to remove the grime and this is the final results any Ideas.
