Environmental staining/toning/tarnishing/discolourization, probably from some sort of chemical reaction to coffee or sofa drinks over time. Not an error coin, post mint damage, no value above face.

I think was some iodine on this coin. Look cool but is just a penny. I will keep for the coolness.

Yes I will keep because I like so much, also I see a variety of 2021 that have steel color, maybe this is one of those, and actually it has DDO for sure, because I finally can see the difference between DM and DD, well not all the time but and still learning, so thank you ladys or and gentleman.

Chemistry speaking, I saw many Cu coins, including the Cu plated with Iron color. Is funny because in my lab we find that if an hepatic person manipulate or touch those coins toning like iron darker. The Ag very black and the AU darker black-blue petroleum.

I like the tones and it may be a DDO but would need better pics to evaluate.

@makecents I tried so many times to take the pictures and that was the best I can took, I don't know why, because I used to take pics to my coins when I need your help and the photos are very good, but in this one I tried every where at the house outside included, I tried my sons and my husband phone too but no good I either way.
