looks like acid ate it.

 

The back is perfectly fine, no smoothness just brown

 

It's damage. The surface wouldn't be that rough looking if it were grease.

 

PMD and I'll second acid - the granular look of the reverse shows differential removal of the copper vs. the nickel

 

Hi
imho,
It looks like washer/dryer damage coin.
There are a lot of scratches on it that makes me think it was tossed around.
When acid eats a coin it bubbles and makes pockets. Here’s a pic.

 

Acid affected this coin.

 

Please @Collecting Nut explain.
How did you come to this conclusion?
Acid Bubbles vs dryer scratches.
Or both?

You could supposedly rub off the image with a lighter acid and then wash it. Probably come out the same way.

 

Not all acids affect metal in the same manner. A dryer coin will be damaged around the rim where it is stuck as the drum turns. This is over the entire face of the coin.

 

Thank you @Collecting Nut

Hope these answers helped you out @Daulton and welcome to ct.
