As with any submission of a graded book, there is a chance of a book coming back with a lower grade. I personally have had books come back with a lower grade but that is a chance I took. If the book is already signed then DWC will need to get book still in the slab and they would need to crack out the book. It all depends if you are really wanting the signature with Stan's autograph. To each there own. For me it depends on the book, if its a book that Romita actually worked on as artist and its a key book I would take that chance. What I usually do is get the book pressed once again to give it a better chance of stay that grade or even coming back a higher grade, which I have done with an ASM 43, previous grade was a 9.2 and it came back a 9.4, so your choice and good luck.
