You've certainly come across comics sealed in a rigid, transparent plastic case, bearing a colored label with a number between 0.5 and 10.0. Those are CGC comics: comics certified and graded by the Certified Guaranty Company, the world reference for professional evaluation of American comics.
You've certainly come across comics sealed in a rigid, transparent plastic case, bearing a colored label with a number between 0.5 and 10.0. Those are CGC comics: comics certified and graded by the Certified Guaranty Company, the world reference for professional evaluation of American comics.
Since its founding in 2000, CGC has transformed the collectible comics market. A CGC 9.8-graded comic can be worth several times more than an ungraded copy in the same apparent condition. But what is comic grading exactly? How does the grading scale work? And above all, which comics actually deserve to be sent to CGC? This complete guide answers all these questions.
What is CGC?
The Certified Guaranty Company (CGC) is an American company based in Sarasota, Florida, founded in 2000. Its core activity: independent evaluation and certification of comic preservation condition. CGC is to comics what PSA is to sports cards, or what GIA is to diamonds: an independent reference whose word stands in the marketplace.
The process is simple in theory: you send your comic to CGC, their experts examine it in detail, assign a grade on a precise scale, and return it sealed in a slab: an airtight plastic case that physically protects the comic and guarantees no one can alter it after certification.
The CGC slab is tamper-proof by design. If the plastic is broken or the seal altered, certification is no longer valid. This physical integrity is what gives the certification its value: you know exactly what condition the comic is in, evaluated by independent experts.
CGC grades not only modern comics (since the 1980s), but also comics from Golden Age (1938–1956), Silver Age (1956–1970), Bronze Age (1970–1985), and Copper Age (1985–1991). It also offers specialized services for magazines, newspaper comics, and signed comics.
The CGC grading scale: 0.5 to 10.0
The CGC scale is the universal reference for rating a comic's preservation condition. It runs from 0.5 (Poor) to 10.0 (Gem Mint), with about twenty intermediate grades. Each grade corresponds to a precise physical condition.
| Grade | Label | Description | Value impact |
|---|---|---|---|
| 0.5 | Poor | Very damaged comic, cover torn or missing, many stains, pages possibly missing. | Historical value only. Choice for very rare Golden Age. |
| 1.0 – 1.8 | Fair / Fair+ | Cover still attached but very worn. Major tears, pronounced stains, yellowed or fragile pages. | Low. Acceptable only for completing a Golden Age collection. |
| 2.0 – 2.5 | Good / Good+ | Cover intact but worn, damaged edges, small stains, slightly yellowed pages. Readable but clearly used. | Low to moderate depending on the issue's rarity. |
| 3.0 – 4.0 | Very Good | Nice overall condition despite visible wear. Small reading marks, light oxidation. Presentable for a collection. | Moderate. Reasonable entry point for popular Silver Age. |
| 5.0 – 6.0 | Fine | Nice copy with light wear. A few small marks, slight staple visibility, spine may be slightly rolled. | Good. Acceptable for the majority of serious collections. |
| 7.0 – 8.0 | Very Fine | Very nice condition. Light wear traces only, vivid colors, white or slightly cream pages. Few defects. | Very good. Widely valued on the resale market. |
| 9.0 – 9.4 | Near Mint | Near perfect. Very slight barely-visible defects. White pages, perfectly preserved colors, no notable wear. | Excellent. Minimum target for modern key issues. |
| 9.6 | Near Mint+ | Single barely-perceptible defect. Practically perfect in every way. | Very high. The minimum for premium resale on key issues. |
| 9.8 | Mint | Almost perfect. Tiny defect visible only under strong light. The most common grade for quality new comics. | Excellent to exceptional. Gold standard for modern key issues. |
| 9.9 – 10.0 | Gem Mint / Pristine | Absolute perfection. No perceptible defect from any angle or light. Extremely rare. | Exceptional. A 10.0 can multiply a 9.8's value 10x or more. |
The 9.8 grade is the most sought-after and most common among high-quality graded comics. Reaching 9.9 or 10.0 is exceptional — CGC has awarded very few 10.0 grades in its history, reserved for absolutely pristine copies often pulled directly from unopened publisher cartons.
Why get a comic graded?
CGC certification addresses several distinct goals depending on your collector situation:
Guaranteed authenticity
The CGC label certifies the comic is authentic and non-restored. No retouching, no repair — what you buy is exactly what's described. Crucial for Golden and Silver Age comics.
Durable physical protection
The slab protects the comic from humidity, UV, dust, and handling. A comic in its slab doesn't degrade anymore and can be stored or displayed risk-free.
Significant valuation
A CGC 9.8-graded comic sells on average 2x to 5x more than an ungraded copy in the same apparent condition, thanks to the confidence certification inspires in buyers.
Easier resale
On eBay, Heritage Auctions, or ComicLink, CGC-graded comics attract more buyers, higher prices, and reduce post-sale disputes: the condition is independently certified.
Which comics deserve to be sent to CGC?
Sending a comic to CGC costs money and time. So it's essential to carefully choose which comics deserve certification. Here are the categories that almost systematically justify grading:
High-potential key issues
A key issue is a number containing a major event: first appearance of a character, hero's death, origin story, first iconic cover. Examples: Amazing Fantasy #15 (first Spider-Man), Incredible Hulk #181 (first Wolverine), New Mutants #98 (first Deadpool). These comics are often worth hundreds to thousands of dollars even in average condition — grading can significantly multiply their value.
Golden Age and Silver Age comics
Any comic published before 1970 deserves special attention. Their rarity and age mean even average-condition copies hold significant value. CGC certification guarantees authenticity (no hidden restoration) and precise condition — two determining criteria for vintage collector pieces.
Comics signed by authors or artists
A Stan Lee, Jack Kirby, Todd McFarlane, or Jim Lee signature can multiply a comic's value. But an unattested signature can also raise suspicion. The CGC Signature Series program (yellow label) certifies signatures obtained in the presence of a CGC witness at official events — a valuable authenticity guarantee for collectors and potential buyers.
Variants and limited editions
Rare variant covers, limited-run editions, and printing errors are often ideal grading candidates. Their value depends directly on their rarity and condition — two criteria CGC documents and officially certifies.
Practical rule: if your comic is worth more than $110 ungraded and you think it could reach 9.6 or better, grading is probably worthwhile. Under $55, grading fees (rate + membership + shipping) often exceed the potential benefit.
The CGC submission process: steps, costs, timelines
Sending a comic to CGC happens in several steps. Here's the complete procedure:
Create an account and join CGC
Visit cgccomics.com and create an account. An annual membership is required (about $39/year for the base level, with higher levels offering discounts on grading fees). Membership gives access to the online submission portal.
Choose a service level
CGC offers several service levels differentiated by processing time and maximum declared value of the comic:
| Service | Estimated delay | Approx. fee | Max value |
|---|---|---|---|
| Economy | 6–9 months | ~$38/comic | $400 |
| Standard | 3–6 months | ~$50/comic | $1,000 |
| Express | ~45 days | ~$75/comic | $2,500 |
| Walk-Through | 2–3 days | ~$150/comic | Unlimited |
Rates change regularly. See cgccomics.com for current rates.
Prepare and pack your comics
Each comic must be placed in a protective sleeve (Mylar preferred) with a backing board. CGC provides precise packaging instructions to prevent damage during shipping. Bad packaging can degrade a comic's condition before it even reaches the experts.
Fill out the online submission form
Through the CGC portal, register each comic to send: exact title, issue, year, publisher, declared value. This info is used to calculate insurance fees and identify the comic in the system. Print the form and include it in your package.
Ship the package and track submission
Ship via a carrier with tracking and insurance (FedEx or UPS recommended). Once received by CGC, you can track submission status online, from receipt until finished slabs ship out.
Receiving slabs and logging in your collection
Your comics come back encapsulated in their slabs with CGC grade. That's where My Comics Collection comes in: immediately log the grade, certification number, and add a photo of the slab for complete tracking of your certified collection.
