PCGR PR 65 1890 V nickel. There are interesting polish marks that are toned and vanish under the devices. It's tough to photograph because of reflections, but I will try tomorrow.
I would leave it alone - very nice coin, but not sure it would make MS. Then again a cross over to NGC might or might not make. Maybe a CAC sticker would help when you go to sell it. Just my humble opinion. I have a new 58+ - really nice coin in hand, but mine is definitely not worth a re-submit.
Your coin looks better than many of the low mint state range coins I have seen that have obvious friction. Congratulations on your new purchase.
