AU-50 (About Uncirculated) - Sharp legends and devices show only a trace of wear on the highest points. There must be some remaining mint luster.
AU-50 This is for "About Uncirculated" (the grade) and "50" (the numerical designation of that grade). Also called "Almost Uncirculated-50." This is the lowest of the four AU grades, with the others being AU53, AU55, and AU58.
AU-50 to AU-55 grade SLQs with around two-thirds head detail are not expensive and are good values for collectors. A PCGS or NGC graded AU-55 1918-D, for example, would be likely to be priced below $250.

But these were heavily saved by collectors and dealers, and today the 1931-S brings a very nominal price (about $24 in AU-50), considering its rarity. By a quirk of fate, the number of nickels struck at San Francisco in 1931 was larger than would have otherwise been the case.

Of course, some proof coins are impossible to distinguish as proofs once they are worn beyond a certain point. Therefore, circulated proofs may also be graded by their circulated grade level (i.e.. VF-20 or AU-50), especially when there is some doubt as to their proof status.
