Going with MS64 as well, see a couple very fine hairline scratches that keep it from going above 64 IMO
No mint sets made 82 83 to find one in MS rare.i found this in a coin roll.2020 quarters and 21 quarters are junk compared to this.Thanks pal for input .Good luck on your errors training.
My gut tells me it has a rub but if wrong then MS-64 looks right. It's a $3 coin with a rub and $10 without.
