Please.. NO MORE PICTURES! Nothing special going on. Not a D mint mark. Just some circulation damage on the area in question. And circulation wear.
I agree with our fellow enthusiasts. Just a circulated nickel with damage. Your photos continue to improve.
There is no mint mark that I can see. It was minted in Philadelphia and is very common. It’s also well worn from circulation, 71 of it.
lol - yes. That one is mine. I had to have one and a strong reverse passed through my LCS. I snapped it up!
