What PR66 means
A 2003-S silver 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.
