I have been noticing a great many YouTube videos posted lately in which people are demonstrating that the books inside of a CGC slab do not match the original book with that same CGC Cert ID#. I believe the books were swapped in the slab and then reholdered at CGC

This made me wonder two things
1) Is book swapping being done to books that are NOT reholdered. and if so
2) how can it be detected and avoided

This video is my exploration of some possibilities. I may be completely wrong.
