Thank you all for the feedback. I completely agree with the general assessment that this is a very generous grade. I bought the book knowing about the back cover tear. The seller had not disclosed that said tear included several interior pages... That being said, I paid a midgrade price and I also didn't know about the Mark Jewelers insert either so even stevens I guess. This is for my PC. I'm not looking to flip the book and I'd certainly disclose the defects if I did. The book does present beautifully. If not for the tears, it would likely grade in the low 9.0's. Shockingly, the grader notes do not disclose the interior tears. CGC definitely needs to get its act together. See below:
