Oh, I certainly think a book *can* be, but I've seen plenty of books that you posted which have obvious flaws that would keep it from being considered a 9.8 by the most respected third-party grading outlet (CGC), or by Overstreet's Grading Guide. If a Divad 9.8 uses different criteria for grading, you should list that criteria in your auctions. Otherwise, you're being deceptive, as people expect that, without qualifying your grade with your criteria, you're employing the accepted industry standards.
