It's hard to tell. I see very little in terms of bag marks, but the luster seems less than I would hope for such a mark free coin. I'll toss in a guess of MS65
The surfaces look really nice as does the strike. Your pictures make the luster look off but I'm guessing it is okay. I think they graded it MS66.
You need more light on your pictures. Either change your settings to make it brighter, or change your lighting. These pictures are hiding what I'm pretty sure is a very nice coin. Anyways, keep in mind that I'm grading the pictures here: Strike: 64 Luster: ? Eye Appeal: 65 Contact Marks: 65- My tentative grade will be 65PL. The obverse strike is poor, but the reverse is good. Absolutely impossible to tell the luster with those pictures (which also make it hard to figure out the eye appeal). I am concerned about the spot on the obverse to the right of the date. The fields appear to have mirrored surfaces. The cheek looks quite clean, and the fields are smooth, but there are a few marks on the breast which will limit the grade. So, with these pics I wouldn't be surprised with a 66PL, but I also wouldn't be surprised if things are hiding that we can't see and it is a 64PL.
I see what looks like some field chatter in front of her face. The cheek and hair and reverse are nice though. I also think that the fields are pretty deep. My Guess is 65pl
I am sticking at 65. Likely PL The coin isn't as clean looking in this set of pictures but that could be some die polish striations. I think that is what you are seeing.
I was going to say 66 based on the first set of images but the second set have me at 65. Maybe PL, hard to tell from the images.
MS 64 PL ...with the added photos, I would say a few too many marks to be higher (original photos suggested a 65/66 grade)
I'll go with '65, but I do like Jasons' assessment. And 'can' the PL.........I think it's regular.........
Strike: 65 (It's pretty good for an O mint) Luster: 66 Eye Appeal: 65 Surface Condition: 65PL obverse 66PL reverse Net to 65PL Overall grade: 65PL
