Grading is generally done by a third party company, PCGS is one of the most well respected companies for grading, as well as NGC. Jeff can give you an estimated grade on a coin, but it won't be an exact grade. PCGS and NGC will give an exact grade and then seal it in a capsule. It will also get a unique serial number that can be tracked on their website. Grading can be quite expensive too, so I would only have it graded if it's a very good, high end coin. Also, every reputable dealer and collector recognize PCGS and NGC grading.
