Last year I sent in two comic books to be cleaned ,pressed, and graded. Finally, today, I saw that everything is done and is due to be shipped to me tomorrow (7-25). After reviewing my order I saw my Predator #1 is graded a 7.5. Luckily I was given grader's notes and it said "there were spine stress lines to the cover and fingerprints on the cover". I thought pressing may take care of the stress lines but apparently not, so it is what it is. What confuses me is how are there fingerprints after I specifically paid to have CGC clean it? I understand dry cleaning may not fix the issue but I paid for a press and clean. FYI I have zero interest in selling these comics and I just want them for my personal collection so the grade doesn't really matter as much to me. I am curious if I am missing something here and I know you all probably have the answer.
