A coin grading designation used primarily by PCGS and NGC for uncirculated coins, abbreviated as MS followed by a number from 60 to 70 (e.g., MS-65, MS-70).

MS-60 represents an uncirculated coin with significant marks; MS-65 represents a choice uncirculated coin; MS-70 represents a perfect coin with no flaws visible at 5x magnification. The price gap between MS-65 and MS-67 on key date coins can be substantial.
