When collecting coins, one of the most important things to understand is how their condition is evaluated. This process is called coin grading and it plays a major role in determining a coin’s value. Three terms you will often come across are Mint State, Nearly Uncirculated, and Professional Coin Grading Service. Each of these refers to different aspects of how a coin is assessed and certified.

The term MS refers to coins still in their original mint condition. These coins are in pristine condition as they were when they left the mint. Mint State coins range from MS60 to MS70, with MS70 being a perfect coin with no wear and no flaws visible under magnification. Even small scratches or surface blemishes can lower the grade. Collectors often seek high Mint State grades because these coins are scarce and アンティーク コイン retain their fresh shine and fine detail.

AU indicates coins that have seen only trace amounts of use. These coins show only the slightest signs of wear, usually on the prominent features. They may have been handled lightly but still retain nearly full original shine. The AU range spans AU50 through AU58. The higher the number, the minimal contact and the stronger the original luster. AU coins are a smart alternative for those who want near perfect coins but at a lower cost than full Mint State examples.

PCGS stands for Professional Coin Grading Service. It is one of the most respected independent graders in the world. When a coin is sent to PCGS, it is evaluated by trained specialists who determine its grade based on industry-leading guidelines. The coin is then sealed in a protective plastic holder with a certification label displaying its rating, provenance, and key metadata. This process, called encapsulation, helps avoid deterioration and tampering, and gives buyers assurance of its quality. PCGS is widely respected across the numismatic community because of its accuracy and track record.

Understanding these terms helps you make informed purchases when buying or selling coins. Whether you are looking for a perfectly graded Mint State specimen or a well preserved AU58 piece, knowing the grade and the certifying authority can help you determine its market worth. Always look for coins graded by reputable services like PCGS to ensure you are avoiding overpaying for misrepresented coins.
