photograde is a great site to learn from as was mentioned above. It will just take some experience to be able to grade close (I say close because I don't believe anyone gets it right 100% of the time) and the more coins you look at the better you will see the little subtle differences. I believe it is better to see the coins in hand over trying to grade by pictures because these subtle differences can be exaggerated or understated by the photos, but you can still learn allot by comparing photos to one another I just prefer the in hand approach
