CGC is the leading comic book collector grading and slabbing service. Naturally, where there is a market originator and leder, there will be competition. Such as PGX, which has come under controversy in the past.

Well, here's a new one. A comic creator is claiming he bought a Fantastic Four comic in PGX 7.5 slabbed condition for $10,000 but, with doubts about its status, had it regraded by, we presume, CGC, who knocked it down to a 5.0, a significant difference in condition and value.

And now, My News LA is reporting that Nash Tennant of Sherman Oaks is suing PGX Comics, alleging breach of contract, fraud, civil conspiracy and negligence. The lawsuit also states "The difference between a 7.5 comic book and a 5.0 comic book is extremely large."
