There is no word corresponding to "condition" in English. Condition is usually used to describe the appearance of a coin, which means "condition". But this word is too abstract and vague, so professionals will use the word grade, which means "level" or "grade". The verb is rating and grading.

2. Coin grading originated in Europe and the United States. The earliest grading method in the United States also used vague words to give Coin classification, the more complete letter grade system in the later period mainly includes poor (Poor or PO), general (Fair or Fr), almost good (AlmostGood or AG), good (Good or G), very good (VeryGood or VG), and exquisite (Fine or F), Very Fine (VF or VF), Extra Fine (ExtraFine or XF), Almost Uncirculated (AU), Uncirculated (Uncirculated or Unc) and Brilliant Uncirculated (BU) .

In the 1950s, William H. Sheldon first proposed the Sheldon standard (also known as: Sheldon 70-point rating) in his book. This standard uses numbers to indicate the age of coins, with the range of numbers being 1-70. Specific levels include: BS-1, FR-2, AG-3, G-4, G-6, VG-8, VG-10, F-12, F-15, VF-20, VF-25, VF -30, VF-35, XF-40, XF-45, AU-50, AU-53, AU-55, Au-58, MS-60, MS-61, MS-62, MS-63, MS-64 , MS-65, MS-66, MS-67, MS-68, MS-69 and MS-70. Here MS is the abbreviation of MintState, which means like it was just minted. The higher the grade, the greater the difference between grades. However, if you want to determine the grade of a coin through personal observation, you need a lot of experience and practice to develop a sharp eye. This is the case for appraisal staff in top grading companies. Some highly trained experts. In fact, the difference between MS69 and MS70 can only be seen through a microscope. This set of grades applies to common coins. For proof coins, a similar set of standards applies, ranging from PF1 to PF70.
