Is it worth grading a comic?

What a submission costs, all in

The tier fee is the number everyone quotes. It isn't the number you pay. A single book moving through CGC picks up five separate costs, and three of them are easy to forget until the invoice lands. Every figure below follows CGC's published submission schedule, checked August 2026.

Tier fee

Roughly $27–45 per book for modern and standard tiers, set by declared value and age. Vintage and high-value books move to pricier tiers.

Handling

About $5 per book, charged on top of the tier. It applies whether the book comes back a 9.8 or a 6.0.

Shipping in

Your cost to get the book there, packed well enough to survive it. Cheap per book on a large submission, expensive on a single one.

Return shipping and insurance

Charged back to you, and it scales with declared value. A slab is heavier and more fragile than a raw book in a bag.

The wait

Around 45 days on standard tiers, longer when a speculation cycle floods the queue. If you're selling into a spike, the spike may be over.

Add those up and a modern book that looked like a $32 decision is closer to $60 before you've sold anything. That's the real hurdle the upgrade has to clear. The full tier-by-tier breakdown is on our comic grading cost page, and current queue times are tracked on the CGC turnaround page.

The question that decides it

Ask a forum whether to grade a book and you'll get twelve opinions about what grade it'll pull. Interesting, but it isn't the decision. Two books can both grade 9.4 and only one of them should be sent.

What separates them is the spread — the gap between what the book sells for raw and what it sells for slabbed at that grade. On a common modern with a print run in the hundreds of thousands, the spread is thin, because slabbing doesn't make a book scarce. On a key with genuine demand at high grade, the spread is where the whole hobby's money lives.

So the arithmetic runs: slabbed comp at your expected grade, minus raw comp, minus every cost above, minus the fees you'll pay on the sale. If what's left is positive by enough to be worth six weeks, send it. If it isn't, the book is worth more in a bag and board, today, with the money still in your pocket.

A worked example, line by line

Here are two books, both estimated at a 9.4 band, both modern, both submitted on the same tier. One is worth sending. One isn't. Nothing about the grading changes between them.

The common modern loses $30 by being graded well. That's the case almost nobody runs the numbers on, because a 9.4 feels like a win. It is a win — it's just a win that costs $30 to collect.

Your break-even grade

Flip the arithmetic and it gets more useful. Instead of asking what the book will grade, ask what grade it needs to hit before the submission pays for itself. That number is the break-even grade, and it's the single most decision-relevant figure for any book you're weighing.

Read that column and the decision stops being about the grade. This book breaks even at 9.2. If your honest assessment is that it's a 9.4 or better, send it — you have a whole grade of headroom. If you think it's a 9.0 with a chance at 9.2, you're paying $67 for a coin flip. The grading scale guide covers what separates those two grades in practice, and it's usually less than people expect.

If it comes back half a grade under

Every grade estimate has a spread, including a professional one. Two CGC graders can see the same book differently, which is why the same issue gets resubmitted and regraded across the hobby every week. So the useful question isn't "what will it get?" but "does the answer survive being wrong by half a point?"

Run the numbers at your expected grade, then run them again half a grade lower. If both come back positive, the decision is safe and you can stop thinking about it. If the lower one flips to a loss, you're not making a submission decision — you're making a bet, and you should size it accordingly.

When pressing changes the answer

Pressing removes non-colour-breaking spine ticks, bends and light waviness. On the right book it moves a half grade, sometimes a full one. On the wrong book it does nothing and you've added $15–25 and another few weeks to a submission that was already marginal.

The test is the same as everything else here: does the pressing cost less than the grade bump is worth? A press that moves a book from 9.2 to 9.6 on the table above turns $3 into $346, which is not a close call. A press that moves a common modern from 9.4 to 9.6 turns a $30 loss into a slightly smaller loss. Our guide to which defects pressing fixes covers the ones worth paying for, and pressing and resubmitting a book that's already slabbed covers the crack-and-repress case.

How to decide, in four questions

Answer these about your book, in order. The first "no" ends it.

1. Is there a real slabbed comp? Not an asking price — a completed sale, in the last few months, at a grade near yours. No comp means no arithmetic, and no arithmetic means you're guessing.
2. Is the spread bigger than about $70? That's roughly what a single modern submission costs all in. Under it, the book has to be exceptional at grade to be worth sending.
3. Does the decision survive half a grade of error? Run it one band lower. If that flips it to a loss, treat it as a bet rather than a plan.
4. Do you need the money in the next two months? Around 45 days in the queue, plus listing and selling time. If the answer's yes, sell it raw.

Four yeses and it's worth grading. Anything else and the honest answer is that this particular book, at this particular moment, is worth more raw. That's not a disappointing result — it's $67 you didn't spend.

ComicMintAI runs those four questions from a photo and returns the verdict: GO, NO-GO, or press first. It gives you a grade band with a confidence level rather than a single number, because a band is what an honest estimate looks like. When the band straddles your break-even grade, it says so instead of picking a side.

Who this doesn't help

If you're grading for certification rather than resale — an insurance schedule, an estate valuation, a book you'll never sell — the arithmetic on this page doesn't apply, because you're not trying to make the spread. The slab is the point. Same goes for signature witnessing, where the value comes from the label and not the number.

And if you're a dealer moving volume, you already grade by eye faster than any tool can help with. The book on your bench is not the reader this page was written for.
