Hi all, completely new here. Looking to submit some of my books from the 90s, and just came across a mind boggling error from the store my mother used to pick then up from. The store would hold issues and give a 10 % discount. Apparently they wrote my last name and 10% on tape with a ballpoint pen and now that I'm examining, LEFT AN IMPRESSION ON THE BOOK(s) (two so far)!
Is this something that "pressing" would help with? Is this something that would take a 9 point something and knock it down to 8 or lower? Make it not worth grading/encapsulating?
