Yall - I've sold 750 copies of my book. This is absolutely incredible. If you haven't had a chance to pick up my tutorial, now is your chance. This is the book I wish I had when I was learning to grade coins. It is based on a series of posts on the NGC forums that translated to the Cointalk Forums. I walk through each aspect of grading, why coins look the way they do, and how to evaluate them. Everyone who is really interested in evaluating coins should read this book. It is available on Amazon here: https://www.amazon.com/Art-Science-Grading-Coins/dp/1492356107
