Which of the Sheldon Grades Between 1-70 include About Uncirculated?
About Uncirculated comprises points 50-58 on the Sheldon grading scale. These coins may have seen some circulation, but it would be minimal. These will range from coins with signs of wear on high points in the design and some remaining luster to coins with virtually full luster and the slightest friction on the highest points.
AU graded coins will have low enough wear that they may be mistaken for Uncirculated coins and the criteria used for these is as follows:
| Number | Grade | Code | Description |
| 50 | About Uncirculated | AU, AU50 | Traces of wear at the high points of the coin. About half of the mint luster remains. |
| 55 | Choice About Uncirculated | Ch. AU, AU55 | Full detail with light friction on the high points. Three fourths of the original luster remain. |
| 58 | Choice About Uncirculated | Ch. AU, AU58 | Almost all of the original mint luster remains. Only the slightest friction is apparent on the highest points. |
