First, I will say the grading of coins is strictly a matter of opinion. It's sort of like beauty being in the eye of the beholder [what is beautiful to one may not be to another]. There are established guidelines, however, which will give you a pretty good idea of what the grade of your coin is. When a coin is in the "in between" grades [could be one grade or could be in the next higher grade] is where opinion comes in and opinions vary. There are coin guides which describe the various grades of each type of coin available at retail bookstores. If you have an old coin and just want to know what grade it is without a lot of study, then you could take it to a coin dealer and have him grade it for you. But remember, it is still just an opinion.
The best thing to do is send it to a third party grading service. They will grade the coin for a fee. This will give you an accurate grade of the coin. You can also take it to a coin collector or use a free online guide like PCGS.
