There's a new service coming out in 2020 to have your protective slab graded.

I hear it will be a pink sticker that you can have affixed to a laminated piece of paper with a hologram that can be kept with the holder of the card. The sticker on the laminated holographic paper will be proof that the holder is in the top 5% of holders in terms of the 3 C's of holder condition (cut, clarity, centering). They also check for evidence of filling out of imperfections from the seams or join areas left from the plastic injection molding process. They can detect if additional plastic has been added to clean up nicks and scrapes on the older too. I think they use lasers to check for cracks.

If base graded card in the original holder is worth less than $500, you can qualify for bulk submission rates. Of course you can always pay a premium to get a quicker turnaround for your sticker.
