In numismatics, Mint State (MS) coins are those that have never been circulated and remain in their original condition as they left the mint. They are graded on the Sheldon Coin Grading Scale , which ranges from MS-60 to MS-70, [according to PCGS].
The Sheldon Scale assigns a numerical value from 1 to 70 to coins, with higher numbers indicating better condition. For Mint State coins, this means a range of MS-60 to MS-70.
- MS-70: Considered a perfect coin, showing no post-production imperfections under 5x magnification.
- MS-60: A coin that is technically uncirculated, but may have numerous contact marks, weak strike, or dull luster.
Professional coin grading services, such as PCGS and NGC, use the Sheldon Scale and consider the following factors when grading Mint State coins:
- Strike: The sharpness and completeness of the coin’s design details, [says PCGS].
- Luster: The strength and pattern of light reflection from the coin’s surface.
- Surface Preservation: The condition of the coin’s surface, particularly the presence of marks, scratches, or other imperfections.
- Eye Appeal: The overall visual attractiveness of the coin, taking into account factors like toning and strike quality.
Note: Surface preservation is considered the most critical factor, accounting for approximately 40% of the overall grade.
Grading provides a standardized method for assessing and comparing the condition of coins, which is crucial for determining their market value and collectibility. Higher-grade coins, particularly Mint State coins, typically command higher prices due to their rarity and superior preservation.
While collectors can learn to estimate a coin’s grade, professional grading by a reputable service like PCGS or NGC is recommended for accuracy and credibility, especially for valuable or rare coins. These services authenticate, grade, and encapsulate coins in secure holders, providing buyers and sellers with confidence in their transactions.
