What AU58 means
A 1970 Washington quarter with no mint mark in About Uncirculated (AU-58) is as close to uncirculated as a circulated coin gets: the lustre is nearly complete and the only wear is a faint rub across the high points of Washington’s hair above and behind the ear that shows when the coin is tilted under a light. Many are better-looking coins than a low mint state example of the same date, and they sell for less.
A slab, a dealer’s list or a price guide may write this grade AU-58. They are the same grade and the same 1970 Washington quarter with no mint mark.
