ChatGPT summary of scam
The CGC Reholder Scam involved replacing high-grade comics in CGC slabs with lower-grade ones, then having them reholdered by CGC. This exploited a loophole where CGC’s reholdering process didn’t reassess the grade of the comic. The scammer would then sell these comics, falsely representing them as high-grade due to the CGC certification. This led to the sale of numerous fraudulent comics, misleading buyers who relied on CGC’s grading for authenticity and value.
If the “tamper proof” slabs for comics are this easily broken into and swapped, the immediate question that comes to my mind is: How easy could this be done to card holders; and has this already happened?
