Comic Book Grading Guide

Everything collectors should know before submitting books to CGC and other graders — plus how existing CBCS slabs fit the market today.

Foundations

What is comic book grading?

Third-party grading sends your comic to an independent company that evaluates physical condition, checks for many types of restoration, and seals the book in a tamper-evident holder called a slab. The label shows a numeric grade, publication details, and a certification number you can verify online.

Collectors use grading for authenticity of condition, long-term preservation, insurance documentation, and easier comparison when buying or selling — especially on key issues and high-grade copies.

Full 10-point scale (NG – 10.0)

Half-point steps from 0.5 through 8.5. Between 9.0 and 10.0, graders use 0.2 increments (9.0, 9.2, 9.4, 9.6, 9.8, 9.9, 10.0). NG indicates no standard numeric grade was assigned (No Grade).

Major grading companies

Each company has different label programs, fees, and market perception. Confirm current submission terms on official sites before shipping books. CBCS is no longer accepting new submissions as of April 17, 2026; use CGC for new grading unless another active grader fits your needs.

CGC

Long-standing market leader

Certified Guaranty Company pioneered modern comic encapsulation and maintains one of the hobby’s largest census databases. Many auction houses and dealers reference CGC slabs routinely.

Strengths

  • Strong resale liquidity on high-end keys
  • Extensive census and cert lookup tools
  • Widely recognized signature and pedigree programs

Considerations

  • Premium fees at higher service tiers
  • Turnaround varies with demand — check current estimates
  • Crack-out/resubmit culture can pressure over-submitting

CGC generally commands the strongest resale premiums in today’s market, especially on golden/silver keys and books where census population matters to buyers.

CBCS

Submissions closed — April 2026

CBCS is no longer accepting new submissions

As of April 17, 2026, CBCS has closed its submission program. Population reports, order tracking, and grader notes remain available on cbcscomics.com. Existing CBCS slabs continue to trade in the secondary market.

Comic Book Certification Service was a major CGC alternative for encapsulation, signature programs, and free grader notes. Collectors still encounter CBCS slabs when buying and selling — but new books should be submitted to an active grader such as CGC.

Strengths

  • Existing slabs remain widely recognized in the hobby
  • Free grader notes via QR code on CBCS labels
  • Population reports and cert lookup tools still online

Considerations

  • New submissions are not accepted (closed April 17, 2026)
  • No option for newly acquired raw books needing fresh grading
  • Some buyers still prefer CGC on highest-tier keys

Treat CBCS as an active label in the resale market, not a current submission path. For new grading, use CGC or another company that is accepting books. Verify holder integrity and cert numbers when buying CBCS slabs.

PGX

Historical third-party grader

PGX operated as an earlier encapsulation service. You may encounter PGX slabs in the secondary market on older inventory. Verify holder integrity and buyer demand before pricing or purchasing.

Strengths

  • Legacy slabs appear on vintage listings
  • Useful context for estate and long-held collections

Considerations

  • Limited role in today’s primary submission market
  • Resale demand is niche compared with CGC/CBCS
  • Research current holder policies before buying or selling

Treat PGX as a historical label — not a default choice for new submissions when maximizing liquidity is the goal.

Decision

Should you grade a comic?

Grading makes sense when the slab improves protection, documents condition, or helps resale on books with real demand. Consider era, rarity, expected grade, fees, and whether you plan to keep or sell the book.

Modern commons, sentimental readers, and damaged copies often stay raw. Keys, sharp high-potential copies, and verified signature candidates are typical submission targets.

Pros

  • Protects and preserves a book in a tamper-evident holder
  • Documents condition for insurance, display, and resale
  • Can improve buyer confidence on key issues and high grades
  • Supports witnessed signature programs where applicable
  • Creates a permanent cert number for verification

Cons

  • Fees, shipping, and insurance add real cost
  • Low grades on common books often hurt more than help
  • Grading is subjective within published standards
  • Slabbing makes reading the book impractical
  • Undisclosed restoration or defects may receive qualified labels

Preparation

Cleaning & pressing

Pressing uses controlled heat and pressure to reduce some non-color-breaking defects. Cleaning removes surface soil — often through professional dry cleaning, not household chemicals.

Many collectors press before grading when defects are eligible, but pressing does not guarantee a higher grade. Graders still judge color breaks, stains, rust, and structure.

May improve (with pros)

  • Non-color-breaking dents and shallow bends
  • Some spine ticks and light waviness (case by case)
  • Minor surface soil when professionally dry cleaned

Cannot fix

  • Color-breaking spine stress and creases
  • Stains, rust, mold, and water damage
  • Missing pieces, tears, and tape pulls with paper loss
  • Trimming, restoration, and color touch

Process

How to submit books

  1. Create an account

    Register on the grader’s website. You will need contact info, return shipping preferences, and payment on file.

  2. Select a service tier

    Choose a tier based on declared value and how quickly you need books back. Economy tiers typically take longer; express tiers cost more.

  3. Complete the submission form

    List each book with title, issue, year, publisher, declared value, and any special services (signatures, pressing, minimum grade).

  4. Pack books safely

    Use rigid mailers, corner protection, and moisture-safe materials. Never tape directly on a comic or bag.

  5. Ship insured

    Use a tracked courier service with insurance matching declared value. Keep photos and tracking numbers.

  6. Grading & encapsulation

    The facility grades, quality-checks, and seals books in holders. Status updates appear in your online account.

  7. Receive your slabs

    Inspect holders on arrival. Verify cert numbers online before listing or storing long term.

Typical turnaround (general ranges)

  • Economy / value tiersOften several months during busy periods
  • Standard tiersTypically weeks to a few months
  • Express / walkthroughDays to a few weeks when offered — premium pricing

Reference

Common grading terms

Raw
A comic not encapsulated by a third-party grader. Condition is subjective until professionally graded or expertly described.
Slab
Industry nickname for a graded, sealed holder. Protects the book and displays the certification label.
Pressing
Controlled heat and pressure to reduce some non-color-breaking defects. Must be disclosed when restoration rules apply.
Cleaning
Surface soil removal — often dry cleaning by professionals. Not the same as washing or bleaching.
Color break
A crease or bend that breaks ink on the cover or interior — generally hurts grade more than a non-color-breaking fold.
Restoration
Work beyond normal wear: color touch, piece replacement, trimming, etc. Graders may note this on labels.
Signature Series
Programs where signatures are witnessed or verified per grader rules and recorded on the label.
Universal label
Standard blue-style label for most graded books without special pedigree or program designation.
Qualified label
A numeric grade plus a stated defect (missing stamp, detached staple, etc.). Read the qualifier, not just the number.
White pages
Interior page color designation — brighter pages can support higher grades on some eras.
Off-white pages
Slightly aged page tone — common on silver and bronze books; affects grade context.
Newton rings
Rainbow-like reflection in slab plastic, often from inner well contact — cosmetic, not a grade defect.
Newsstand
Distribution variant often with markings (no price tag, UPC, etc.) — can carry premiums on some issues.
Direct edition
Sold through direct market shops; often lacks newsstand markings. Variant premiums vary by title.
Pedigree
Documented collection provenance accepted by a grader — can add historical premium beyond the numeric grade.

Avoid

Common gotchas & mistakes

Fingerprints and oils

Handle by edges only. Oils can cause defects visible under grading lights.

Humidity damage

Store in climate-stable spaces. Swelling, waviness, and mold are difficult to reverse.

Over-cleaning

Aggressive erasers or chemicals can abrade paper and lower grades or trigger restoration notes.

Amateur pressing

DIY pressing on valuable books risks irreversible damage — especially on brittle or foil covers.

Trimming & restoration

Trimmed edges and color touch are serious issues. Graders detect many treatments.

Shipping damage

Most preventable with rigid mailers, proper void fill, and insurance.

Cracked slabs

Use official reholder services. Opening slabs yourself breaks tamper evidence.

Modern foil covers

Require experienced pressing judgment — easy to damage with excessive heat.

Signatures ≠ automatic profit

Unverified signatures may not qualify for premium labels. Research witness rules first.
