What PR68 means
A 1940 proof Washington quarter with no mint mark in Proof (PR-68) is as good as the date is usually found: the surfaces are untouched, the open fields of Washington’s cheek and jaw show nothing under magnification, and the only thing separating it from the top of the scale is a trace of haze or a single pinpoint mark.
A slab, a dealer’s list or a price guide may write this grade PR-68, PF68 or PF-68. They are the same grade and the same 1940 proof Washington quarter with no mint mark.
