What PR66 means
A 1968-S proof Washington quarter in Proof (PR-66) is better than the run of surviving proofs of its date: the mirrors are unbroken, the open fields of Washington’s cheek and jaw are clean under magnification, and the contrast between field and device is what the grade is really paying for.
A slab, a dealer’s list or a price guide may write this grade PR-66, PF66 or PF-66. They are the same grade and the same 1968-S proof Washington quarter.
