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 Mint State scale spans from MS60 up to MS70, with MS70 representing a flawless specimen under 5x magnification. Even microscopic abrasions or bag marks can lower the grade. Collectors often seek top-tier MS specimens because these coins are highly uncommon and retain their fresh shine and sharp design elements.
