I don't know what to think, except that PCGS holds to entirely lowball standards for a "67." The Jack Lee example, depicted twice at Heritage, has gouges all over the place including a very prominent one just below the eye. Your coin is a league ahead of that one. All the same, yours has two notable gouges in the right obverse field, and almost every reverse letter has a visible ding of some sort. MS67 - to me - is the point at which you start bringing magnification to bear when grading.
If the Jack Lee coin is a 67, yours deserves consideration as a 68. As it is, I'm almost convinced PCGS is grading these by comparison to coins they've already seen, as opposed to an objective standard having nothing to do with what's in the field.
