CGC Help Center

CGC does not buy or sell comic books and does not have a financial interest in the collectibles that it certifies. In fact, employees of CGC are prohibited from buying and selling certified collectibles commercially.

CGC will discuss the details of each transaction with the original submitter ONLY to provide complete confidentiality for all parties. CGC will not release any information concerning the identity of the original submitter without permission. As part of CGC's internal processes, complete anonymity is also ensured by a system of checks and balances. Comic invoices are numerically barcoded upon receipt by our receiving team. Graders do not have any computer access to submitter information.

CGC offers the following guarantees: CGC guarantees that CGC holders are free of defects deemed to be distracting, significant or otherwise outside of normal tolerances, according to CGC's good faith determination. Important note: Because of the fragile nature of most paper collectibles, the grade is not guaranteed (other than for trading cards). Read the full CGC Guarantee here.

No. CGC is an impartial third-party grading company and does not provide an appraisal or evaluation of a book's worth. This information can be obtained from other sources such as gpanalysis.com or the Overstreet Price Guide.
