If the CGC stated as part of the grading proces that your new case might have Newton rings, hairline cracks, scratches, scuffs, debris inside, schmutz on the case, etc so be it.
I'm paying for a new undamaged product and that is what I expect.
Right now, this is what they state:
Crystal-clear Display
The crystal-clear plastic’s superior optics unleash a comic’s true color and vibrancy. The redesigned label is cleaner and easier to read, showcasing the grade and even more details about the book, and allowing you to easily identify the book from both the front and back.
As part of the grading process:
Step 6/7 Quality Control
A Quality Control specialist carefully inspects the collectible, CGC label and CGC holder. All of the certification details are reviewed for accuracy and the holder is checked for any defects or contaminants.
As far as ME's go, I am at a 25% return rate on over 400 books over the past 15 months.
And that is not sending them ALL back, on some I missed something or the defect was tolerable.
I just got back a 25 ME book sub. Originally ALL of them had a scuffed inner well (looks like someone took sandpaper to it).
Four went back AGAIN (three had debris in the case and one had white spots inside the case).
The majority of the books have large buffing compound smudges/streaks I have to remove with wax.
Over half had side edge cracks.
This ME was inspected by COMICS QC #2.
What a joke.
They can keep doing it until they figure out how to do it right.
