What is M65 rating on coins?

The M65 rating on coins refers to a specific grade within the Sheldon scale, which is used to assess the quality and condition of coins. An M65 coin is considered "Mint State 65," indicating that it has minimal imperfections and retains high levels of luster and eye appeal. Coins in this grade typically show only very light contact marks or hairlines, making them particularly desirable to collectors. The M65 designation is part of a broader grading system that helps gauge a coin's value and marketability.
