lewis, I would recommend sorting the coins into two groups, those graded by PCGS and NGC (Numismatic Guaranty Corporation) in one group and the rest in another group. PCGS and NGC are the two most trusted third party grading services. Doesn't mean they are always right on their grading but they are heads above the others. The non PCGS and NGC slabbed coins you can upload pictures to your file hosting service so the people on this forum can help you with the confirming the grades of them.
In the PCGS / NGC pile you can post a list of the coins and their grades here so members can give an idea of an approximate retail value so you know what you have there. For example PCGS $1 1887-S MS-65 or NGC $1 1883-CC MS-63.
