A little guess the grade, Washington proof.

It's hard to grade from a pic, but what would you grade this one.

There is a strange color change in the area of the upper neck adjacent to the jaw. Could just be shadow but could be haze or other discoloration. Also a strange tiny rectangular mark above the ear--could just be glare but can't tell
Does not look CAM to me.
Really good hair detail.
Based on the scan could be anything from pr 64 to 68.
Edited to add: Like I said, 68

That's either an extremely bad image or the graders were drunk.

I'm not sure. It might be a mechanical error. If you search the TT site, the other 71 Washingtons appear properly imaged and apparently use the same lighting. I was looking at the 71s because I have one that is very nice, and I was trying to see how much market grading goes on with the date.

If that is a mechanical error, then wouldn't PCGS's coin buy back would be void for the future coin owner?
