A system of grading which was originally introduced by the late Dr. William H. Sheldon, for the purpose of grading large cents. The system was adapted to all coins in the early 1970's. The Sheldon Scale, as applied today, incorporates numerical grades 1 through 70 to correspond with various descriptive grades as follows:
- Poor - 1
- Fair - 2
- Almost Good - 3
- Good - 4, 6
- Very Good - 8, 10
- Fine - 12, 15
- Very Fine - 20, 25, 30, 35
- Extremely Fine - 40, 45
- Almost Uncirculated - 50, 53, 55, 58
- Mint State - 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70.
