1997-D Nickel annealing errors?

Found this in a roll the other day. Could it be an annealing error? For reference I included a pic of a slabbed specimen that I own (seller's pic) since my phone doesn't take very good pictures. In hand it looks like the slabbed one with the soft coppery coloring. Opinions?

With how dull the nickel areas look I would lean towards ED.

 

I agree, the copper colored areas have a spotted nature and variation in color intensity that makes me think environmental damage. The graded example shows smooth and even copper areas.

 

Okay I'll go with that. Thank you. What in the environment would cause coppery coloring like that? Just curious so I'll know better if I come across another.

 

Don’t forget the copper that’s in the nickel.

 

ED.

 

Remember that a nickel is something like 75% copper, there are many elements in the ground that will turn a nickel red colors. Look up a few metal detecting threads.

 

I'll do that. Thank you.

 

So; what everyone is saying is that PCGS is wrong??

 

No. Saying the original poster was wrong.

 

The OP coin doesn't seem to be an error. It could be ED, it could be toning. It could have been in the ground and exposed to pollutants and other elements that oxidized the coin that color.
