What is page quality on a graded comic, and why does it matter?

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

Short answerPage quality describes the colour of a comic's interior paper, from White through Off-White, Cream and Tan to Brittle. It is printed on the grading label separately from the numeric grade. Whiter pages mean the paper has aged less, so between two copies with the same grade the one with whiter pages is worth more and is a safer long-term hold.

The scale used on labels

CGC prints one of these on every label, in this order from best to worst:

  • White
  • Off-White to White
  • Off-White
  • Cream to Off-White
  • Cream
  • Tan to Cream
  • Tan
  • Brittle

The assessment is made on the interior pages, not the cover. A book with a bright cover can still have tan pages if it was stored somewhere warm.

Why paper changes colour

Newsprint is acidic. Over decades the acids break down the paper, turning it yellow, then brown, and finally brittle enough to crack when the book is opened. Heat, humidity, light and contact with other acidic materials (cardboard, old bags) accelerate it. Books stored cold and dry — the reason pedigree collections from cool climates are so prized — stay white for a very long time.

How it affects value

Page quality does not change the numeric grade, but the market prices it:

  • For Silver and Bronze Age books, white pages are expected on high-grade copies and cream pages are a discount.
  • For Golden Age books, off-white is common and white pages are a genuine premium.
  • Brittle pages are a serious problem at any grade: the book cannot be handled safely and many collectors avoid it entirely.

When two listings look identical, compare the page quality on the label before comparing prices.

Can it be improved?

No. Deacidification can slow further deterioration but does not reverse the colour, and chemical whitening counts as restoration. What you can do is stop it getting worse: store slabs and raw books cool, dry and dark, in acid-free materials. See How to store and preserve comics.

Every listing in the store shows the page quality from the label in its specifications.

Frequently asked

Is off-white to white the same as white?
No. White is the top of the scale; off-white to white means the pages are very slightly toned. The price difference between the two is small on most books but real on high-grade keys.
Does CBCS report page quality?
Yes. CBCS uses a comparable scale and prints it on the label.

    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.
