Tracking your CGC graded comics in a spreadsheet becomes unmanageable after 10 slabs.Between certification numbers, grades, labels, cost prices and market values, a dedicated tool is needed to centralize and monitor the evolution of this portfolio. Here's how to organize the monitoring of your slabs without losing anything.
CGC monitoring and grading in your collection: how to centralize everything
Most comic book collectors start by accumulating raw copies — comics in sleeves, stored in longboxes. Then comes the day when a value number deserves to be submitted for CGC grading. And from that moment on, the complexity of managing the collection fundamentally changes. A CGC slab isn't just a comic book in a transparent case — it's a certified object with a unique number, a specific grade, a specific label, a submission history, and a market value that evolves independently of the equivalent raw comic book. This guide shows you how to centralize everything efficiently.
Why tracking graded comics is different
A raw comic book in a Mylar sleeve requires some basic information: title, number, publisher, estimated condition, purchase price. It's simple, and a spreadsheet or even a notebook can be enough.
A CGC slab changes the situation. Each graded specimen is an entity in itself, uniquely identified in the CGC database. The information to follow is increasing:
- CGC certification number: the unique 10-digit identifier of your slab, verifiable on the CGC website.
- Rank awarded: from 0.5 to 10.0. Half a point difference can represent hundreds of euros in value difference.
- Type of label: Universal (blue), Signature Series (yellow), Qualified (green), Restored (purple). Each label has a direct impact on the rating.
- Submission date and return date: useful for calculating processing times and holding time.
- Total cost price: purchase price of the raw comic book + CGC submission fees (between €25 and €150 depending on the tier) + shipping costs + insurance.
- Current market value: distinct from the cost price, it fluctuates and must be updated.
Without a suitable tool, managing this data quickly becomes a headache. An Excel spreadsheet can work for 5 slabs, but once you have 20 or 30, manual value updates, profitability calculations, and cross-referencing with your raw comics become unmanageable.
The CGC Process: What to Follow at Each Step
Before submission: choosing what to grade
Not all comics deserve to be ranked. CGC submission fees start at around €25 for the Economy tier and rise to over €150 for the Walk-Through tier. Add round-trip shipping costs (€15 to €40 depending on the country) and insurance, and the total cost of grading is between €50 and €200 per comic.
The basic rule:only grade a comic if its potential graded value significantly exceeds its gross price plus grading fees. An Amazing Spider-Man #300 in apparent Near Mint condition makes sense: going from "raw in very good condition" to "CGC 9.6" can triple the value. A current issue from the 90s in good condition, on the other hand, is probably not worth the cost of submission.
Write down the comics you plan to submit in your app, along with an estimate of the apparent condition. This pre-selection helps you prioritize and budget your submissions.
During submission: track transit
Once your comic is sent to CGC, it may take between 4 weeks (Modern tier) and 6 months or more (Economy tier) before you get it back. During this period, the comic is no longer physically in your collection, but it is still part of it.
Mark the comic as "grading" in your app. Note the shipping date, the chosen third party, and the package tracking number. If you are submitting multiple comics at the same time — which is recommended to amortize shipping costs — each issue should have its own entry with its submission status.
On return: save the result
The moment of truth. Your comic comes back with a grade. Now is the time to update your catalog with the definitive information: CGC certification number, grade obtained, type of label, and photo of the slab if you want to visually document your collection.
Also calculate thetotal cost priceof the slab: initial purchase price + submission fee + shipping costs + insurance. This figure is essential to assess the profitability of your grading and to know whether the slab is a gain or loss in value compared to your investment.
The value of a slab: why it evolves differently
A fundamental point that many collectors underestimate: the value of a CGC slab does not follow the same dynamic as a raw comic book. Two phenomena overlap.
La prime de grade
The market country for certification. An Amazing Spider-Man #300 in Very Fine/Near Mint condition without grading can sell for around €300. The same example with a CGC 9.6 grade can reach €800 to €1,000. Certification provides an objective guarantee that the market values, sometimes spectacularly.
But be careful: the grade bonus is strongly non-linear. The difference between a CGC 9.4 and a CGC 9.6 can be 30 to 50%. The difference between a 9.6 and a 9.8 can double or triple the value. And the gap between a 9.8 and a 10.0 (Gem Mint) is often astronomical — when a 10.0 exists, which is rare.
La prime de liquidité
A CGC slab is easier to sell than a raw comic book of equivalent value. The buyer doesn't need to trust your condition estimate — CGC has done that for them. This additional liquidity has value in itself, especially for high value numbers where trust in the state is a major issue.
Mixed collection: two worlds, one tool
Most collectors have a mixed collection: hundreds of raw comics in their longboxes, and a few dozen (sometimes more) slabs on a shelf or in specialized boxes. Managing these two worlds separately — a spreadsheet for the slabs, an app for the rough ones — creates blind spots.
The ideal is a single tool that distinguishes the two categories while grouping them in the same inventory. When you view your run of Amazing Spider-Man, you want to see both your raw copies and your slabs, with their respective information. When you calculate the total value of your collection for insurance, you want a number that includes everything.
My Comics Collection is designed for this: each entry can be marked as "raw" or "graded", with fields specific to each category. The total value calculation integrates both, and the reports distinguish the "raw" and the "graded" part of your collection.
Insurance: why slabs require rigorous monitoring
A CGC 9.8 slab from a key issue can be worth several thousand euros. Yet most collectors don't cover their slabs properly. Standard home insurance policies typically cap coverage for collectibles at a few hundred dollars, far below the actual value of a slab collection.
To properly insure your slabs, your insurer needs a detailed inventory: certification number, grade, photos, and current market value. A collection management tool that centralizes this data allows you to generate this document in a few clicks, instead of manually reconstituting it with each update.
Update your slab values at least once a year — ratings fluctuate, sometimes significantly. An Amazing Spider-Man #361 (first Carnage) in CGC 9.8 saw its value vary from €300 to more than €800 in a few years, depending on announcements of the film adaptation.
Quand faire grader un comics : la matrice de décision
To decide if a comic deserves grading, ask yourself four questions:
1. What is its current gross value?If the comic is worth less than €50 in gross, the grading costs (€50 to €200) may not be profitable, unless you are very confident about a high grade (9.6+).
2. What state is he really in?Be honest. If you rate your copy at Fine (6.0) or below, grading probably won't provide enough of a premium to justify the fee. Grading is most profitable for copies in Very Fine/Near Mint (8.0+).
3. What is the price gap between grades?View recent sales for the issue in question at various grades. If the difference between an 8.0 and a 9.0 is €100 for this number, grading can be profitable. If the difference is €20, it probably isn't.
4. What is your goal?Whether you're grading to protect a sentimental comic or for personal satisfaction, financial profitability is not the only criterion. If you are grading to invest or resell, the calculation must be strictly financial.
Organize your submissions by batch
Submitting a single comic to CGC is rarely optimal. Shipping costs are fixed regardless of the number of comics sent, and some services (CGC Club membership, for example) offer discounts on multiple submissions.
The recommended strategy: accumulate 5-10 comics to submit, then send them all in one batch. This amortizes shipping costs and allows you to take advantage of the cheapest third party submissions for less urgent issues while speeding up the processing of priority parts.
Note each comic awaiting submission in your app with the tag "to be graded". When the batch reaches a critical size, launch the submission. This systematic tracking avoids forgetting a comic in a pile or submitting the same issue twice (yes, it happens).

The total cost depends on the tier chosen and the declared value of the comic. For the Economy tier (comics worth less than $400), count on approximately $25 in CGC fees. Add 15 to 40€ round-trip shipping costs (more if you are in France or Europe, the CGC headquarters being in the United States) and insurance in proportion to the value. In practice, the total cost is between €50 and €200 per comic depending on the tier and destination. Grouped submissions allow you to reduce shipping costs.
Deadlines vary considerably depending on the tier. Walk-Through (the most expensive) can be processed in a few days. Express takes approximately 10 to 15 business days. The Standard is between 30 and 60 days. Economy can take 3 to 6 months, sometimes longer during peak periods. To these times, add the round-trip postal transit time. Choose the tier based on the urgency and value of the comic.
Not necessarily, but grading is most profitable for comics of significant value. A key issue in very good condition (first appearances, pivot numbers) is the ideal candidate. But some collectors also grade sentimental comics or copies of complete series to protect them permanently. The financial criterion is not the only one — protection and certification also have value in themselves.
CGC (Certified Guaranty Company) and CBCS (Comic Book Certification Service) are the two main grading services. CGC is the historical leader, with the largest database and the best liquidity in the secondary market. CBCS offers similar services at sometimes lower prices, but its slabs are generally less highly rated for resale. Most serious collectors use CGC for high value coins and CBCS as an alternative for secondary submissions.
CGC ratings change depending on the market. Sites like GoCollect and GPAnalysis compile recent sales by title, number and grade. My Comics Collection integrates this data to give you an updated value estimate for each slab. The ideal is to check the values at least once a quarter, and update your inventory accordingly — this is essential for insurance and to know the true value of your portfolio.
Yes, it's possible via the "reholder" service or by breaking the slab to resubmit the comic. However, regrading is rarely profitable. CGC may assign a lower grade upon re-evaluation, and resubmission fees are added. Regrading is only justified if you believe that an obvious error has been made, or if the condition of the slab (damaged case) requires re-encapsulation.
