MS 55 based on the obverse...nicks and cuts and wear on Kennedy's hair....the reverse is pristine, but that doesn't carry the coin. No higher than MS 55 and maybe as low as XF 45.
Just my guesses, but I added an absolutely PERFECT Kennedy 64 to a batch that I sent in to get graded 2 weeks ago and it only graded out at MS65. Crazy, there isn't a single flaw.
Anyway, there are a few minor flaws on the obverse of this one, and I'm basing my guesses on that.
