What does the CGC guarantee cover?

Due to the fragile nature of comic books, CGC does not offer a grading guarantee. However, CGC does offer the following guarantee: a) CGC guarantees that two or more comic professionals will review every comic book submitted for grading. b) CGC guarantees its holder to be free of defects. Defective holders will be replaced at no charge, except when it is determined (at CGC's sole discretion) that the holder was subjected to abuse, or if damage is the result of storage in a hazardous environment. c) CGC guarantees that all books it certifies are authentic, as described on the CGC grading label.

What are your grading standards for comic books?

The CGC grading standard was developed by taking a consensus of grades assigned to a variety of comic books by a nationwide pool of experts that included comic book dealers and leading collectors. CGC realizes that comic book grading is an art that develops from years of experience, and while a consistently applied standard of grading eliminates much of the subjectivity and risk, grading itself is NOT an exact science and remains subjective. That's why it is reasonable to expect that slight variances may exist between CGC grading standards and the standards of some dealers and collectors. CGC strives to consistently apply the most accurate grading standard to assure that the grades of comic books are properly represented to the widest possible audience.

Does CGC grade magazine-size or treasury-size books?

CGC does grade magazine-size books but does not grade treasury-size books.

Does CGC perform pressing or dry cleaning?

CGC does perform pressing, dry cleaning or any similar treatments for comic books. To learn more, visit the website or call +44 (0) 20 3968 3848. Please note that pressing and/or dry cleaning performed incorrectly or on a comic book exhibiting certain flaws — such as slightly brittle pages, weak spine, cover wear at staple and/or other defects — can damage the comic book and lower its grade.

Does CGC certify sealed poly-bagged books?

CGC does not certify sealed poly-bagged books. To have a poly-bagged book certified by CGC, you must remove the book from its poly-bag or send written approval authorizing CGC to remove it. The words “Poly-bag removed” appear on the CGC label.

How do I know that the comic I'm buying is the same book CGC certified?

CGC has a number of technologically advanced security measures built into its holders. Once a comic is certified, any future attempt to open the holder will be visibly evident.

Why should I return a label of an opened or "cracked out" certified book?

You should always return a label of any opened certified book. This helps keep the CGC Census accurate. The CGC Census is a detailed database of all the comic books we have graded and their respective grades, and it has become an important resource in assessing the availability of certified comic books.

What is a pedigree?

A pedigree is an exceptional and widely known original owner collection. CGC considers the following criteria when determining Pedigree status of a collection: The collection must be original owner. The collection must be of vintage material. The collection must consist of a considerable number of comics. The collection must be high-grade. For detailed information, please visit our Pedigree resources page.

Does CGC attend comic cons and trade shows?

Yes, CGC attends the major comic cons. At these shows, CGC representatives are available to answer your questions and take submissions.

Signature Series

Does CGC grade autographed books?

CGC does grade autographed books. If a book is signed without a CGC authorized representative witness present, it will receive a Qualified label (green), and will receive a Qualified grade. No authentication of signature is provided for books that do not have a CGC Signature Series label.

What is the CGC Signature Series label?

The prestigious CGC Signature Series label (yellow) is applied to comic books that have been signed by someone of significance to the comic, under the direct observation of a CGC authorized representative witness. The signatures are authenticated by CGC and the labels indicate who signed the book, the date it was signed and, in some cases, the location of where it was signed.

What if I get the book signed before submitting the book to CGC?

Unfortunately, if the signing is not witnessed by someone authorized by CGC, then the signature cannot be authenticated for the Signature Series label. Testimonials, photographs, and video recordings are not accepted.

Are restored comic books eligible for CGC Signature Series?

Yes. Restored comic books are eligible for the CGC Signature Series Restored label, which is yellow with a purple bar across the top. The degree of restoration and details of the work performed are noted on the label. As with all CGC Signature Series books, the signing must be witnessed by a CGC authorized representative.

What signings are approved for CGC Signature Series?

Most signings are prearranged. Any signing where a CGC authorized representative witness is in attendance is eligible. This includes comic book conventions and public signings, such as ones that occur at comic book stores. In select instances, CGC may accept signed books directly from the signer/publisher.

How can I set up my own Signature Series signing?

If you are already a CGC Authorized Dealer, it may be easier than you think! Contact CGC Customer Service

How do I get my book signed if I am not going to a convention?

CGC can arrange for an authorized facilitator to acquire signatures on behalf of customers.

CGC Grading Process

What is the CGC grading process?

When a submission is received by CGC’s London office, it is opened by trained staff under security cameras. Each collectible is entered into CGC’s proprietary system and assigned a unique identification number and barcode that will track it throughout every stage of the grading process. Relevant submission information, including a description of each book, is entered into a proprietary computer tracking system.

CGC’s London office sends submissions with insurance coverage (based on the submitter’s declared value) to CGC headquarters in the US for authentication, grading and encapsulation. Upon arrival at CGC headquarters, the submission’s status is updated, and the collectibles are separated from the submission paperwork so that CGC’s graders never know the submitter's identity, which ensures impartiality.

Collectibles that are determined to be authentic are graded according to CGC’s grading standards and encapsulated in CGC’s secure, tamper-evident holders designed for long-term preservation. They are then rechecked for accuracy and quality, imaged and returned to CGC’s London office, again with insurance coverage based on the submitter’s declared value.

What measures are in place at CGC to ensure the safety of my books?

CGC headquarters is a secure 6,000-square-meter purpose‐built facility with two large vaults, a staff of armed guards and more than 150 security cameras. CGC’s London office also has extensive security measures in place to protect books in its care.

All submissions are opened under security cameras and each book is immediately assigned a unique identification number that is used to track it throughout every stage of the grading process. All books are fully insured while in CGC’s possession and are handled only by trained staff.

When I submit my books, what assurances can you offer with regard to confidentiality and anonymity?

CGC will discuss the details of each transaction only with the original submitter to provide complete confidentiality for all parties. CGC will not release any information concerning the certification of your comics without permission. As part of CGC's internal processes, complete anonymity is also ensured by a system of internal checks and balances. Comics receive generic barcoding upon receipt and CGC’s separate receiving department does not convey any information about the submitter to the graders. Therefore, the comic owner’s identity is also completely unknown to CGC graders.

Do you buy, sell or appraise comics and magazines?

No. CGC does not buy, sell or appraise books to maintain their independence. CGC is focused on providing expert and impartial assessments of authenticity and grade.

CGC is described as independent and third-party. What does that mean?

CGC does not buy or sell comic books and do not have a financial interest in the comic books that they certify. In fact, CGC employees are prohibited from buying and selling comic books commercially.

Holdered Comics and Magazines

Why does CGC use different colored labels and what do they mean?

CGC uses different colored labels to easily demarcate each grade category. CGC labels can be blue, green, purple or yellow, or a mixture of colors. Click here to view the full description of each label.

Will your holder increase or decrease the safety of my comics?

The CGC holder is designed to securely hold your comic book and provide years of protection from many environmental hazards. All of the materials used inside the CGC holder are tested and proven to be archival-safe, and the holder is designed to be the first line of defense in a prudent plan for storage. CGC’s research and design team created a holder that is truly unique and unrivaled for its protection and preservation of comic books.

What if I undervalue my comic book?

If CGC determines that a comic book's value likely exceeds the maximum value allowed under the selected tier, CGC may move the collectible to a higher tier and adjust the conservation or grading fees accordingly. It is important that you assign an accurate value to the collectibles that you submit to CGC.

Grades are available to view online when a submission's status is "Shipped."

If I remove my collectible from its CGC holder, what should I do with the label?

This helps to make the CGC Comics Population Report more accurate. Please note that removing a collectible from its CGC holder will void any guarantee provided by the company. If you would like it to be re-encapsulated by CGC, it would need to be submitted for grading as a raw (ungraded) collectible.
