Seeing this comment and noticing that my guess is the same as others, could it be MS 62 (slider coin with a hint of rub that found its way into a low MS holder)?
No plus grade, it’s an old holder… and it’s certainly not close to a 67. Either she graded MS61 or AU58…?
It looks very similar to the MS-64 example in my collection. I am concerned about the dull area that is on Ms. Liberty’s shin. That might be a rub. This coin was often not the sharpest strike, and the luster is often muted.
