What F15 means
A 1959 Washington quarter with no mint mark in Fine (F-15) is a Fine coin at the better end of the grade: the same moderate, even wear, but the eagle’s individual breast and leg feathers start to show at the centres and the high points of Washington’s hair above and behind the ear hold more of their shape than on a coin graded twelve. The difference between the two is a judgement of degree rather than of kind, which is why they sell so close together.
A slab, a dealer’s list or a price guide may write this grade F-15. They are the same grade and the same 1959 Washington quarter with no mint mark.
