AboutMyCoin1979-S Proof Washington Quarter in PR64
A 1979-S proof Washington quarter graded PR64 is that coin in one particular state of preservation — the date and the mint mark are already fixed, and PR64 is what a grader called the surface that survived.

What PR64 means
A 1979-S proof Washington quarter in Proof (PR-64) is a near-gem proof: the fields are deeply reflective, the open fields of Washington’s cheek and jaw are essentially clean, and what keeps it off the gem grade is a few faint hairlines rather than anything a reader would notice unaided.
A slab, a dealer’s list or a price guide may write this grade PR-64, PF64 or PF-64. They are the same grade and the same 1979-S proof Washington quarter.
