Grading & authentication

What is the CGC census and how do you use it?

Published Sep 14, 2026 · Updated Sep 14, 2026 · 1 min read

Short answerThe CGC census is CGC's public count of every comic it has graded, broken down by title, issue and grade. Looking up a book tells you how many copies exist in each grade and on each label type, which is the single most useful number for judging scarcity and pricing a graded copy.

What it shows

For any issue, the census lists the number of Universal, Signature Series, Restored and Qualified copies CGC has graded, and how many sit at each grade from 0.5 to 10.0. A line such as "9.8: 40 copies, none higher" tells you that 40 encapsulated 9.8s exist and that 9.8 is the highest grade on record for that issue.

How to use it when buying

  • Scarcity at the grade. A 9.6 of a book with three hundred 9.8s is a different proposition from a 9.6 that is the highest graded copy.
  • Top of census. "None higher" and "one of X in 9.8" are the phrases that drive record prices.
  • Sanity-check a price. If a seller claims rarity but the census shows thousands of copies in high grade, the claim is about demand, not supply.

How to use it when selling

Quote the census position in your listing. Serious buyers will check it anyway, and a low population at your grade is your strongest argument.

What it does not show

  • Raw copies. The census counts graded books only. For Modern Age books, most surviving copies have never been graded, so the census understates supply.
  • Resubmissions. When a book is cracked, pressed and regraded, the old entry may remain unless the label is returned to CGC, so populations can be slightly inflated.
  • Sales. The census is a population count, not a price guide. Combine it with realised sales — see How much is my comic worth?.

CBCS publishes a comparable population report for its own slabs. Our listings quote the census position for high-value books in the description.

Frequently asked

Does a low census count guarantee a high price?
No. Scarcity only matters when there is demand. Plenty of obscure books have tiny census counts and little value; the expensive books are scarce and wanted.

    What is a CGC graded comic?

    A CGC graded comic is a comic book that Certified Guaranty Company (CGC) has examined, assigned a numeric grade from 0.5 to 10.0, and sealed in a tamper-evident plastic holder with a label that records the grade, the page quality and any restoration. The holder and label let a buyer trust the condition without opening the book.

    How are comics graded? The 10-point scale explained

    Comics are graded on a 10-point scale that runs from 0.5 (Poor) to 10.0 (Gem Mint), with 25 steps in between. Graders assess the book's structure, surface, spine, corners, page quality and completeness, then assign the highest grade the worst significant defect allows. CGC and CBCS both use this scale, which comes from the Overstreet grading standard.

    CGC vs CBCS: what is the difference?

    CGC (founded 2000) and CBCS (founded 2014) are the two main third-party comic grading companies in the United States. Both grade on the same 10-point scale and encapsulate books in tamper-evident holders. CGC has the larger census and the deeper resale market, so its slabs often carry a modest premium; CBCS is known for its signature verification, which authenticates signatures after the fact rather than requiring a witness.

    What do CGC label colours mean?

    The colour of a CGC label tells you what kind of grade you are looking at before you read a word: blue (Universal) means an unrestored book graded on its own merits, yellow (Signature Series) means a signature witnessed by CGC, purple (Restored) means the book has been repaired or altered, and green (Qualified) means one significant defect has been set aside from the grade.

    What is a Signature Series comic?

    A Signature Series comic is a book that was signed by a creator or celebrity in front of a CGC-authorised witness and then graded and sealed with a yellow label naming the signer. Because the signing was witnessed, the signature is guaranteed authentic without any later analysis. CBCS's equivalent is the yellow Verified Signature label.

    What does “restored” mean on a comic label?

    A restored comic has been repaired or altered to improve its appearance: colour touch to hide wear, tears sealed with glue, missing pieces replaced, edges trimmed, chemical cleaning, re-glossing or pages married in from another copy. CGC and CBCS disclose restoration on a purple label with the extent and quality of the work, and restored copies sell at a steep discount to unrestored copies of the same grade.
