To grade a coin means to evaluate it based on the amount of wear it has. The two most basic ways of describing a coin’s wear are uncirculated, meaning a coin that has no evidence of wear from circulation (used in everyday transactions), and circulated, meaning a coin that has some degree of wear (ranging from a barely-discernible rub to decades of wear that has virtually destroyed the coin’s design).

While there are established systems and processes for grading a coin, it is ultimately a subjective conclusion. One grading service may assign a coin at a higher or lower grade than another service based on the amount of wear a particular grader perceives.

A Brief History of Coin Grading

The Early Years

In the mid-19th century, coin collectors realized the necessity of defining the quality of coins in order to assess their values. A basic system of grading was developed, which consisted of three levels:

  • Good
    Mass circulation has worn the coin, but the details of its design were still visible
  • Fine
    The details of the coin’s design were preserved better than that of a “good” coin, and it retained some of its mint luster
  • Uncirculated
    The details of the coin were clearly defined and it retained a luster near its original mint state.

As the market for coin collecting grew throughout the late 19th and early 20th centuries, it became clear that a more comprehensive grading system was needed. Some coins graded as “fine” were obviously more fine than others, and some “uncirculated” coins had more luster and detail than others.

Terms such as Very Good, Very Fine, Extra Fine, Almost Uncirculated, and Gem Uncirculated began to enter use among collectors as ways of more precisely describing the condition of a particular coin.

A Standard System

In 1948, a well-known numismatist, Dr. William Sheldon, attempted to standardize coin grading with a 1 to 70 grading scale. The Sheldon Scale, as it became known, serves as the basis for today’s professional coin grading services. The original scale is included below.

Original Sheldon Scale

In the 1970’s, the American Numismatic Association adopted a modified version of the Sheldon Scale that is included below.
