Basic Coin Grades
Circulated U.S. Coins
Old or extremely rare coins can be very difficult to find in mint uncirculated condition. While they have accumulated some wear during use, Circulated coins in Good or better condition are coveted by collectors.
Uncirculated and Proof Coins
Uncirculated coins are those that were never intended for circulation in daily commerce. The condition of these coins may vary to some degree because of blemishes, toning or slight imperfections.
The term Proof refers to a manufacturing method that produces coins specifically for collectors. A proof coin typically features sharp detail and a brilliant, mirror-like surface, although proof coins with some wear are often graded using the American Numismatic Association’s (ANA) Coin Grading Scale.
Below is an outline of the Official ANA Grading Standards for United States Coins from the Professional Coin Grading Service. For more information about grading coins, purchase a copy of Official ANA Grading Standards for United States Coins, which includes a complete grading guide for each individual series of United States coins.
