When establishing the value of a coin, condition and rarity are the two most influential factors. Learning how to grade coins is an essential part of the hobby, and is by no means easy. Grading requires practice and experience, and can take years to master.
The Sheldon Scale was developed in 1949 as a method of grading coins and uses scores ranging from 0 (Poor) to 70 (Mint State). While a coin can receive any grade between 0 and 70, the most common grades are outlined below. For more detailed information on grading coins, please review our selection of grading guides.
