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, AU, 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 representing a flawless specimen under 5x magnification. Even minor contact marks or bag marks can lower the grade. Collectors often seek top-tier MS specimens because these coins are rare and retain their mint brilliance and sharp design elements.

About Uncirculated (AU) describes coins with minimal circulation wear. These coins show extremely light friction, usually on the highest points of the design. They may have been briefly used but still retain significant residual brilliance. AU coins are graded from AU50 to AU58. The increasing digit, the minimal contact and アンティーク コイン the greater the shine. AU coins are a popular choice for those who want high-quality uncirculated pieces but at a lower cost than MS65+ coins.

PCGS is short for Professional Coin Grading Service. It is one of the leading third-party grading companies in the world. When a coin is sent to PCGS, it is examined by experts who determine its grade based on strict standards. The coin is then securely housed in a sonically sealed case with a label that includes its grade, verification, and additional data. This process, called certification, helps avoid deterioration and counterfeiting, and gives buyers peace of mind regarding its state. PCGS is trusted by collectors and dealers alike because of its accuracy and prestige.

Understanding these terms helps you make smarter choices 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 who certified it can help you determine its market worth. Always look for coins graded by reputable services like ANACS to ensure you are getting what you pay for.
