To determine the value of a coin, it must be graded. Whether that's done by a professional coin grading service or an experienced coin dealer, there is a set of standards to use. The American Numismatic Association ( ANA ) publishes these standards in The Official American Numismatic Association Grading Standards For United States Coins. You can purchase this book and it will help you grade your own coins, and make a preliminary coin appraisal.
Some of the general grading information from the ANA standards are listed below. For coin-specific grading standards you can refer to the ANA book, or use the links on the right to see examples of grading for selected US coins.

Coin Grading – Coin Appraisal
Coin grading is a shorthand way to describe the state of preservation of a coin;i.e., it is the amount of wear, or "damage," to the surface of a that coin. Thus, e.g., "EF-40" is shorthand for "All design elements show clearly. Traces of mint luster may still show ... etc." There is room for some subjectivity built into the ANA guidelines. But even experts in coin grading may differ in how they interpret the objective coin grading standards. This is important because as a coin gets into the higher coin-grading scores, the difference of moving up or down even one point can make a huge difference in a coin appraisal.
Here is an overview of the coin grading standards established by the ANA:
Proof coins are made in a separate manufacturing process from other coins at the US Mint. Proof coins are not intended for circulation. The mirrorlike finish of proof coins is more susceptible to damage from handling than are general, "business strike" coins.
PROOF-70
–
PROOF-60
PR-70
"The perfect coin. Has a very attractive sharp strike and surface of the highest quality for the variety. ... Eye appeal is attractive and outstanding. ... There are absolutely ... no defects."
PR-65
"... A few small, scattered contact marks, or two larger marks, may be present, and hairlines may show under magnification. ... A few spots may be present ..."
PR-60
"Unattractive, dull, or washed-out fields will exhibit little, if any, mirror-like characteristics. ... Copper coins may be dark, dull and spotted. ... eye appeal is very poor."
Mint state or Uncirculated coins are coins that are intended for general circulation – sometimes called "business strike" coins – but bear few, if any, signs that they actually were circulated. Unlike with Proof coins, there may be variations in the quality of a coin even before it goes into circulation, because of the quality of the mint "strike" or because of how it was stored before circulating ("bag marks," etc.)
