Founded in 2000, CGC is the first independent, impartial, third-party comic book grading service. A proven and respected commitment to integrity, accuracy, consistency and impartiality has made CGC the leader in its field. In fact, in 2007, CGC crossed the million-book mark and has now graded over 2 million comic books.
