I found these on Youtube and although they are quite long, they are very well done. I think they do a very good job in Coin Grading 102 clearing up what their requirements are for their grading designations including the copper color designations (RD, RB, BN), the strike designations (FB, FH), and surface designations (PL, DMPL, CAM, DCAM). I did not watch the portion about moderns, maybe someone who wants to watch it can comment on the quality of that section. Check these videos out guys, I promise they are good.
I watched the first one and just got the email about the second. They have the third made, just not released to the public yet. I plan to watch the second one in the hotel tonight.
I just ran across these and watched them all. By now the third one is up of course. Very informative videos.
