In the United States, the NGC Grading Scale is widely used to accurately and concisely communicate a coin’s condition. While 70 is the highest grade assigned, not all numbers 1–70 are used. In total, there are 30 discrete numerical grades assigned, and 11 of them are assigned to coins that show no evidence of having been in circulation (grades 60–70).
The number of grades allows for exceptional precision when describing the condition of any individual coin or when comparing two similar specimens. While the NGC Grading Scale invites extremely precise descriptions, its major advantage is that grades are assigned by trained and impartial experts. This means that the application of grades is not only precise, but accurate and consistent.
Grading scales vary widely internationally, and almost all use many fewer grades to describe a coin’s condition — some as few as five. This chart describes how grading systems around the world may correspond to the NGC Grading Scale. Since the application of these scales can vary, this should be viewed as a rough guideline only.
