This Nickel is greyish. It has no scratches. Both sides of the coin have distinct color that is not the same as a normal coin. Both sides of the coin is same color. I would grade it high as there is no scratches or ware, however it's grey/black.
It would also help if you eliminated the extraneous background, and then resized the image. If you don't have the software to do this, there is a free download called Photoscape that is available. I wouldn't want to guess what the grade might be without better images. @Lehigh96 is one of our better nickel specialists.
Once again, all I can add is that you really need to educate yourself on errors. Not trying to be disrespectful, just pointing out what I see as obvious.
All coins lie somewhere in the dirt. In fact. Any planet that does not make currency from the most abundant resource like dirt, will always be left to manipulate more than there fair share of dirt.
Two tribes, cave man and gov man. The cave man decided to melt dirt and made some coins from it. The gov man had to signify the coins with dye. And so extracted rare metals and printed coins. However the cave man realized that it takes many years to grow harvest and dye the paper and or coins. So the cave man continues to use the most abundant currency. And says clearly. If you use what is least abundant of the two for currency, currency will be worth less and less as time makes it such. Hear on planet reality. The thing found to be most abundant is to be the medium to all other things.
You know those little bottles with the pharmacists labels on them? Don't forget to take your daily dose.
Curly? As a side note, Curly wasn't really bald. He had a full head of hair, but the producers of their shows thought it would be funnier if he had no hair. (We know he did because you can see their "stubs?" or whatever it's called. Sorry for the side track.
It is possibly done by heating the nickel coin to change the outer surface of it to Nickel Oxide which has that coloration. It is used as coloration in ceramics glazes for deep grey-black color. It has a melting point of nearly 4000 degrees F, so only the surface shows the thin-layer effect. ( Hey , learned a little during my ceramic classes Just saying this is the most likely to me. Jim
