What does MS and PF stand for on coins?
Grading companies use a numeric grading system called the Sheldon grading scale to describe a coin's condition that can range from being poorly struck covered with marks (MS-60) to to a flawless example (MS-70), even after 5x magnification. The numeric grade is typically preceded by an abbreviation that indicates the way the coin was struck and, for circulation issues, its approximate condition.
The two most common types are MS and PF
MS or Mint State refers to a coin struck for circulation—or in the same style as a coin struck for circulation. It also means that the coin grades between 60 and 70. Circulation issues in grades below 60 receive a different prefix based on their adjectival grade range.
PF or Proof issues, are coins that are specially struck for collectors with highly polished dies and planchets. These coins traditionally feature frosted design elements and mirrored fields. The numeric grade of Proof coins is preceded by PF even if the grade is below 60. For example, a 50 is described a PF 50.
