CGC remains the market standard, accounting for roughly 80% of graded comic sales on eBay and Heritage Auctions, with fees ranging from $25 to $150 per book and turnaround times of 30 to 90 days. CBCS, acquired by Beckett in 2018, offers prices 15 to 25% lower and a built-in signature verification service, but its resale value averages 10 to 20% below CGC for an equivalent grade. PGX carries a tarnished reputation and should be avoided for any serious resale, with values running 30 to 50% below a comparable CGC.
Professional grading turns a subjective opinion into certified data. Three services dominate the American market: CGC (Certified Guaranty Company), CBCS (Certified Bonded Comics Sentinel, now rebranded as Certified Comics Authentication Service), and PGX (Professional Grading eXperts). All three grade comics on the same 0.5-to-10.0 scale, but they don't carry the same weight on the secondary market. This guide breaks down each service point by point: market recognition, pricing structure, turnaround times, label format, and resale value at exit. No subjective comparisons — just numbers and facts, so you can decide based on your collection profile, your budget, and your resale horizon.
CGC: the market standard since 2000
The Certified Guaranty Company was founded in 2000 in Sarasota, Florida. It was the first independent grading service dedicated to comics, separate from the existing services for sports cards. CGC has graded approximately 13 million comics since its founding, including more than 1.2 million in 2024 alone. That certified volume exerts real mechanical pressure on the secondary market: a CGC-slabbed comic sells faster and at a more stable price than an equivalent raw copy.
CGC's dominance shows up clearly in sales data. At Heritage Auctions, the world's largest comics auction house, roughly 92% of graded lots sold in 2024 carried a CGC label, 6% a CBCS label, and fewer than 2% other certifications. On eBay, CGC accounts for approximately 78 to 82% of graded comic sales depending on the category. This dominance creates a ratchet effect: a serious buyer pays a premium for CGC because they know the book will command the same premium when they resell it.
The CGC grading scale runs from 0.5 (Poor) to 10.0 (Gem Mint) in increments of 0.2 or 0.4 depending on the tier. The most common grades on the premium market are CGC 9.6 (Near Mint+) and CGC 9.8 (Near Mint/Mint), which together represent roughly 60% of modern graded comics. An Amazing Spider-Man #300 in CGC 9.8 typically sells between $1,800 and $2,400 depending on the timing, compared to $600–$800 in CGC 9.4 and $250–$350 raw in NM condition. The value gap between CGC grades often exceeds a factor of 3 to 5 for key issues.
The black-and-white CGC label with its security hologram, the vacuum-sealed acrylic slab, and the unique 10-digit certification number (verifiable on CGC.com) have become visual industry standards. For the complete submission process and pricing, see the complete CGC grading guide. The detailed fee schedule is documented in CGC tiers and service fees explained.
CBCS: the lower-cost alternative with built-in signature verification
CBCS was launched in 2014 by Steve Borock, who had served as CGC's Primary Grader from 2000 to 2009. The stated goal: offer a competing grading service with a more accessible approach. In 2018, Beckett Media — the established player in sports card grading through Beckett Grading Services — acquired CBCS and folded it into its ecosystem. The acquisition gave CBCS a solid logistics infrastructure and greater visibility in the American market.
The CBCS fee structure mirrors CGC's but sits 15 to 25% lower. For a comic with a declared value of $200, the CBCS standard tier charges roughly $20 to $25, versus $30 to $35 at CGC. For a $1,000 book, the CBCS mid-tier runs $45 to $55, compared to $65 to $80 at CGC. Published turnaround times are comparable, generally 40 to 80 days for consumer-tier submissions.
The most-cited CBCS differentiator is its built-in signature verification program, which doesn't require an officially witnessed signing. Where CGC requires a signature to be obtained at a CGC-witnessed convention appearance to qualify for the yellow Signature Series label, CBCS accepts signatures obtained outside official events through a post-hoc verification process (the Verified Signature Program). This flexibility has attracted collectors who already owned unwitnessed historical signatures — for example, dedications obtained in the 1990s during creator convention tours. For a full breakdown of label types, see CGC label colors and meanings.
The CBCS slab is physically wider than CGC's, with a blue-and-white design, a security hologram, and a QR code in the bottom-right corner for mobile verification. The CBCS slab uses a two-piece shell with a closure system that's immediately recognizable by eye, distinct from the edge-sealed CGC slab. That visual difference makes identification on marketplaces straightforward.
On the secondary market, a CBCS-graded comic sells on average 10 to 20% below an equivalent CGC grade, and sometimes up to 30% less for sought-after key issues. A Walking Dead #1 in CBCS 9.8 was trading around $1,400 to $1,700 in late 2024, versus $1,900 to $2,200 for an identical CGC 9.8. That gap reflects CGC's superior liquidity more than any difference in grading quality, which is broadly comparable according to comparative analyses published by CBSI Comics and GoCollect.
PGX: low market recognition and resale risks
PGX (Professional Grading eXperts) is the third legacy service in the market, founded in 2002. During the 2000s and 2010s, PGX positioned itself as a budget alternative to CGC, with fees often 30 to 40% lower. That aggressive pricing attracted beginning collectors and dealers looking to minimize grading costs.
Several structural problems have damaged PGX's reputation over the years. Reports from independent experts and members of the CGC Collectors Society have consistently flagged grade inflation — meaning PGX assigned notes 0.4 to 0.6 points higher than a CGC or CBCS assessment of the same book. While this inflates the apparent value for sellers in the short term, it has progressively eroded the PGX brand in the eyes of serious buyers.
Documented cases of counterfeit PGX slabs circulating on eBay between 2015 and 2020 made the situation worse. Multiple collectors reported purchasing comics in PGX slabs where the displayed grade didn't match reality, some of which were simple label reproductions with no verifiable certification. PGX does not offer an online lookup system as robust as CGC lookup verify or the CBCS verification system, making authentication difficult.
The secondary market impact is measurable. A PGX 9.8 sells on average 30 to 50% below an equivalent CGC 9.8, and sometimes up to 60% less for in-demand key issues. An X-Men #94 in PGX 9.4 was trading around $800 to $1,100 in late 2024, versus $2,200 to $2,800 for an identical CGC 9.4. This gap means many collectors intentionally buy PGX slabs with the goal of doing a crack-out and resubmitting to CGC to capture the resale premium.
For any collection aimed at long-term preservation or serious resale above $200 per book, PGX is statistically worth avoiding. For low-value comics or strictly personal use with no resale intent, the service remains functional — but the lower entry price no longer offsets the recognition deficit.
Fee structures and turnaround times
All three services use a tiered pricing structure indexed to the comic's declared value and desired return speed. The figures below reflect 2025 market conditions and serve as a general guide — official fee schedules are updated every 12 to 18 months.
CGC's standard fees start around $25 per book for the Economy tier (declared value up to $200, turnaround 60 to 90 days), rise to $35–$45 for the Standard tier (up to $1,000, 45 to 75 days), and reach $75–$150 for the premium Express and WalkThrough tiers (higher values, 20 to 30 days). Add to that optional pressing fees ($15 to $30), insured return shipping (variable by declared value, typically $15 to $80), and any applicable taxes for international shipments. The CGC tiers and service fees article details each tier.
CBCS follows a similar structure positioned 15 to 25% lower. The equivalent Standard tier runs $20 to $35, the mid-tier $40 to $60, and premium tiers $65 to $120. CBCS also offers in-house pressing through Classic Collectible Services (CCS), a longstanding partnership that streamlines the press-and-grade workflow into a single submission.
PGX publishes the lowest fees on the market: $12 to $18 for lower-value comics, $25 to $40 for mid-range books, and $50 to $80 for premium pieces. This attractive pricing structure doesn't hold up against the resale differential described above.
On turnaround, CGC officially quotes 30 to 90 days depending on tier, with frequent delays during high-volume periods (post-convention rushes, major film releases). CBCS advertises 40 to 80 days and tends to hit that window more consistently. PGX quotes 30 to 60 days with wider variance. For collectors shipping internationally, these timelines add to 7 to 14 days of transit each way, for a typical total of 2 to 5 months between drop-off and return.

Labels and slab formats: visual differences
The label and slab are each service's visual signature. These physical elements shape buyer perception and can make resale on marketplaces easier — or harder.
The CGC slab is a vacuum-sealed transparent acrylic case manufactured by Numismatic Conservation Services (CGC's sister company). The interior label is white with a colored border indicating the certification type: blue for Universal, yellow for Signature Series, purple for Restored, green for Qualified. The 10-digit certification number appears in the upper right. The gold-bordered security hologram on the back of the label makes counterfeiting difficult but not impossible. For the full explanation of label colors, see CGC label colors and meanings and the CGC blue label guide.
The CBCS slab is physically wider and thicker than CGC's. The interior label is blue and white with a QR code in the bottom-right corner, enabling mobile verification by pointing a smartphone at it. The colored border system works similarly: blue for Universal, yellow for Verified Signature Program, green for Restored, purple for Authentic. The certification number is shorter (8 digits) and prefixed by an alphanumeric identifier.
The PGX slab falls in between, with a white-and-red label that is smaller than CBCS but wider than CGC. The certification number appears at the bottom of the label with no visible hologram. The less industrial manufacturing of the PGX slab has resulted in sealing defects observed on older specimens (roughly 2002 to 2010), which partly explains reports of comics found altered inside their slabs.
This manufacturing difference has real long-term implications: a slab whose airtightness is not guaranteed no longer protects the comic from humidity, temperature fluctuations, or UV exposure. For a collection stored in a damp basement or in a display case exposed to light, seal quality becomes critical over a 10-to-20-year horizon.
Recognition by auction houses and marketplaces
Beyond the label itself, the institutional recognition of each service determines resale options. It dictates which comics can enter which auctions and how smoothly the process goes.
Heritage Auctions, ComicConnect, and ComicLink — the three most active comics auction houses — accept CGC books without restriction. CBCS books are accepted but are often grouped into lower-reserve lots, reducing exposure to premium buyers. PGX books are sometimes accepted on ComicLink but are virtually absent from major Heritage sales, where curation strongly favors the dominant certification. For selling a key issue valued at $5,000 or more in a major auction, CGC is statistically the path that maximizes the final price.
On eBay, all three services circulate, but with significant price gaps documented month over month on GoCollect and CovrPrice. The same comic at the same grade consistently sells higher in CGC than in CBCS than in PGX. The CGC-to-CBCS differential runs 10 to 20%, and the CGC-to-PGX differential runs 30 to 50%.
On specialty marketplaces like MyComicShop, MileHighComics, or MyComicShop sellers on Amazon, CGC is treated as the standard and CBCS as an acceptable alternative. PGX rarely appears in a featured position and shows up mainly in flash sales or liquidation listings. For collectors selling through classified sites, local buy/sell groups, or specialized social media communities, the gap is less pronounced but still present.

Recommendations by collector profile
The right grading service depends on the value of your comics, your resale timeline, and your overall budget. Three typical profiles cover the majority of situations collectors face.
Profile 1: serious collection with comics valued above $200. For a collector who owns raw key issues worth more than $200 each — books like Amazing Spider-Man #129 (first Punisher), X-Men #94 (Giant-Size All-New X-Men, start of the new era), Walking Dead #1, or Saga #1 first print — the roughly $30 to $50 per-book premium to go CGC instead of CBCS is statistically absorbed by the CGC resale premium. Across 10 comics graded CGC instead of CBCS, the extra $300 to $500 in submission costs is recovered through a resale differential averaging $800 to $1,500. For the most sought-after Spider-Man key issues, see Amazing Spider-Man key issues.
Profile 2: mid-range collection with comics valued between $50 and $200. For a collector looking to grade modern or semi-modern comics at an intermediate value with no immediate intent to sell at a premium, CBCS becomes a mathematically defensible option. The entry fee differential (saving $5 to $15 per book) across a 20-to-30-book lot adds up to $100 to $450 in immediate savings. If the resale horizon is distant (5 to 10 years), the market may shift and the CBCS-to-CGC gap could narrow as the graded comics market continues to grow. See Batman key issues and X-Men key issues to identify which books are grading candidates.
Profile 3: beginning collection or low-value comics. For comics with a raw value below $50, grading is statistically not worth it regardless of which service you use. The all-in cost of grading (submission fee + pressing + shipping + insurance + return) runs roughly $60 to $100 per book, which wipes out the grading premium for low-value pieces. You're better off putting that budget toward archival-quality bags and boards and maintaining a disciplined Comics Manager to preserve your collection. For an organizational approach without grading, see cataloging your comics: methods and guide and managing your comic collection.
Tracking graded comics in a Comics Manager
Regardless of which service you choose, tracking your graded comics in a structured tool becomes necessary once you hit 10 or 15 certified books. Paper records or a basic spreadsheet are no longer sufficient to manage the specific attributes that come with graded comics.
A serious comics collection manager models each graded book with the following fields: certifying service (CGC, CBCS, PGX), certification number, exact grade (e.g., 9.6), label type (Universal, Signature Series, Restored, Qualified), grading date, submission cost, and recent market value. That level of detail lets you calculate performance by certifying service over 5 or 10 years and inform your future submission decisions.
The CGC lookup verify function built into some collection managers lets you verify a CGC certification number by entering the 10-digit code alone. The system pulls the official CGC record in under 5 seconds: grade, label, grading date, series title, and issue number. This verification is invaluable when buying secondhand, to confirm a slab hasn't been tampered with. The subtle difference between CGC 9.8 and 9.6 and between CGC 9.0 and 9.2 carries a measurable price impact.
Multi-service statistical tracking in a single manager surfaces trade-offs that intuition alone can't catch. For example, a collector who realizes after three years that their 12 CBCS books appreciated an average of 8% per year versus 11% for their 18 CGC books can decide to redirect future submissions to CGC, factoring that performance differential into their return-on-investment calculation.
FAQ — CGC, CBCS, and PGX
Why is CGC more expensive than CBCS and PGX?
CGC charges 15 to 25% more than CBCS and 30 to 50% more than PGX. That premium funds a logistics chain proven since 2000, well-established veteran graders, a security infrastructure (hologram, robust online lookup), and brand equity. The higher entry fee is on average offset by the CGC resale premium, which runs 10 to 50% depending on the comic's profile.
Is a CBCS comic worth less than a CGC at the same grade?
Yes, on average. On the eBay and Heritage Auctions secondary market between 2020 and 2025, a CBCS 9.8 sold on average 10 to 20% below an equivalent CGC 9.8. The gap widens to 25 to 30% for certain highly sought Silver Age key issues. This gap reflects CGC's superior liquidity, not any difference in grading quality, which is broadly comparable.
Should PGX always be avoided?
For any collection aimed at long-term preservation or serious resale above $200 per book, yes. The CGC-vs-PGX resale differential commonly exceeds 30 to 50%, which more than erases the 30-to-40% savings at submission. For very low-value comics or strictly personal use with no resale intent, PGX is usable — but offers little collector value beyond basic protection.
Can you convert a CBCS or PGX book to CGC?
Yes, via a crack-out: crack the existing slab, free the comic, and submit it to CGC in a new process. The operation costs the CGC submission fee ($25 to $80 depending on tier) plus the risk of receiving a lower grade on re-evaluation. For PGX books where the grade appears inflated, that risk is real. See the dedicated article: crack case CGC: when and why.
Does CBCS accept signatures obtained outside conventions?
Yes, through its Verified Signature Program (VSP), which allows subsequent authentication of signatures obtained outside official events. CGC, by contrast, requires that a signature be obtained at a CGC-witnessed session to qualify for the yellow Signature Series label. This CBCS flexibility is a genuine selling point for collectors who already own unwitnessed historical signatures.
What value justifies grading a comic?
Empirically, starting at roughly $100 to $150 in raw value, the total grading cost (roughly $60 to $100 for a CGC economy tier) begins to be offset by the grading premium. Below $50 raw value, grading is statistically a losing proposition. Between $50 and $100, it's a bet on the book's future appreciation.
How do you verify that a CGC or CBCS slab isn't counterfeit?
For CGC, enter the 10-digit certification number on CGC.com under the Verify section. The official record appears with the grade, label type, grading date, and comic title. For CBCS, scan the label's QR code or use the verify module on the official website. The hologram and slab build quality are secondary indicators.
Do all three services use the same grading scale?
Yes — the 0.5-to-10.0 scale with increments of 0.2 or 0.4 is shared by all three. The Overstreet definitions (Mint, Near Mint, Very Fine, Fine, Very Good, Good, Fair, Poor) are common to all. However, practical application varies: CGC is generally regarded as the strictest, CBCS is slightly more lenient, and PGX has historically been the most generous, with documented discrepancies of 0.4 to 0.6 points on the same comic.
