I have no idea what's going on

acid, chemicals, environmental damage

It certainly didn't leave the Mint like that.

 

I know just needed an idea

 

Could also be glue residue.
Dip it in acetone and it will come right off!

That would be nail polish remover

 

I've seen this type before, it's like adhesive/glue...at first I thought it was a glorious die crack, then I microscoped it and saw it was glue.

 

I'll go with glue as well and maybe an acid too. Soak it in water overnight and see if any of it turns soft or just go ahead and soak it in acetone.

 

Did soak it in distilled water for three days

 

How long do you soak it in acetone?

 

Yes, it's roached.

 

Thank you I soaked it in acetone and no help

 

I did the acetone and no it won't come off

 

How long was the soak and can you tell if the anomalies are indeed raised throughout the areas they're covering?

There's nothing wrong with experimenting on this one and in fact I'd call doing so a good thing since you'll learn from it. Don't be afraid to poke/prod it in ways one wouldn't a collectible example.

 

I soaked about an hour took a blade to it scrubbed it with a brush and when I use my fingernail it is raised

 

Please post a new image of the coin after all you did to the coin.

 

here is the after

 

Looks like the corrosion went thru the copper and barely started to attack the zinc core. Likely attacked by some weak acid. When you physically removed the copper salt (aka: corrosion), you exposed the discolored and very slightly corroded zinc core.
The good news is you were experimenting with a coin worth only $0.01! A very inexpensive lesson in coin conservation.

 

Thank you

 

Who knows what it is. There are glues and other types of plastics that do not react to acetone. Bottom line is it did not leave the mint like that

 

1980 cents were still bronze / 95% copper = no zinc core.
The coin looks to have been coated with clear epoxy ?
You can try applying paint stripper and scratching at the 'melted' epoxy with a toothpick - epoxy resin won't dissolve, just soften.
