Coins grading guide

  Coin grading is not a science but an art that requires a lot of practice. Any person with a fine eye can make an approximate idea on the grade of a coin. 

It is important to know how to grade a coin if we want to estimate its value. As an example .. two coins of the same type but in different grades can cost between few cents and few hundred US dollars. 

Below there is a list with all grades along with their description, American equivalent and a clear image of that grade.
