Which comics belong in a CGC bulk submission
The cheap per-book tier only opens at 25 books, so the box gets filled by whatever's nearest. Every slot costs the same whether the book earns it or not. Rank the pile, draw a cut line, and know exactly which books to swap.
One photo per book. Verdict and expected net, in about 30 seconds.
A CGC bulk submission is a batch of 25 books or more sent on CGC's cheapest per-book tier. The books worth including are the ones whose slabbed-to-raw spread clears the full cost of a slot — roughly $27–45 in tier fees plus about $5 handling and a share of shipping. Rank every candidate by expected net and cut where the number turns negative.
What the 25-book minimum does to you
CGC's cheapest per-book pricing requires a bulk submission of 25 books minimum. That rule is doing something strange to the hobby, and almost nobody notices it. It converts a per-book decision into a quota. You stop asking whether a book is worth sending and start asking what else is in the closet.
The trap is that the discount is real. The cheap tier genuinely costs less per book than sending nine of them on a standard tier. So the instinct to fill the box is sound. What's unsound is filling it without checking, because a slot you didn't earn still costs the tier fee, the roughly $5 handling, its share of shipping both ways, and 45 days of your book being in a queue in Florida instead of in your hands.
Get six of those wrong and you've spent a few hundred dollars turning cheap raw comics into cheap slabbed comics. The single-book version of this arithmetic is on our break-even guide for one comic; this page is what happens when you have to make that call twenty-five times in an afternoon.
Filling the box vs earning the slot
These two sound like the same activity. They produce completely different boxes.
Sorted by what's handy
You pick the 25 best-looking books you own. High grade feels like the criterion, so the pile skews toward clean moderns with nothing wrong with them. They come back 9.6 and 9.8, the slabs look great, and the resale barely moves — because a clean copy of a book with a 300,000 print run isn't scarce at 9.8 either.
Sorted by expected net
You pick the 25 books with the biggest gap between slabbed and raw, after costs. Some of them are mid-grade and scruffy. A 6.0 bronze key can out-earn a 9.8 modern by a factor of ten, because the slab is buying certainty on a book where certainty is worth paying for.
Condition decides the grade. Scarcity and demand decide whether the grade is worth buying.
The rule that reorders most people's pileWhat to rank the pile on
One number per book: expected net. It's built from four inputs, and three of them are things you look up rather than judge.
- Raw comp
- What the book sells for ungraded, from completed sales in the last few months. Not an asking price. Our valuation guide covers where to pull these.
- Slabbed comp at your band
- What a certified copy sells for at the grade you honestly expect — not the grade you're hoping for. Look up two grades, not one, so you can see how fast the price falls.
- Slot cost
- Tier fee plus about $5 handling plus this book's share of shipping both ways. On a 25-book box the shipping share is small, which is the whole point of going bulk.
- Sale fees
- Whatever the venue takes when you sell the slab. Around 13% is a common all-in figure once payment processing is counted. It scales with price, so it bites hardest on the good books.
Expected net = slabbed comp − raw comp − slot cost − sale fees. That's it. Rank descending, and the pile sorts itself into an order that almost never matches the order you'd have picked by eye.
A worked pile, ranked
Here's a pile of candidates run through that formula, on a bulk slot costing $36 all in — $27 tier, $5 handling, $4 of shipping. Ten rows out of a longer list, spanning the range you'd expect from a real closet.
| Candidate | Raw | Slabbed | Fees + slot | Expected net |
|---|---|---|---|---|
| Silver key, band 5.5–6.5 | $420 | $980 | −$163 | +$397 |
| Bronze first appearance, 8.0–9.0 | $180 | $470 | −$97 | +$193 |
| Copper key, 9.0–9.4 | $95 | $290 | −$74 | +$121 |
| Modern first appearance, 9.4–9.8 | $70 | $240 | −$67 | +$103 |
| Bronze horror, 6.0–7.0 | $110 | $215 | −$64 | +$41 |
| Low-run variant, 9.6–9.8 | $58 | $135 | −$54 | +$23 |
| Copper minor key, 8.5–9.2 | $45 | $105 | −$50 | +$10 |
| Cut line — everything below loses money on its own | ||||
| Common modern, 9.4–9.8 | $34 | $72 | −$45 | −$7 |
| Bronze filler, 5.0–6.0 | $28 | $55 | −$43 | −$16 |
| Modern reprint, 9.6–9.8 | $12 | $28 | −$40 | −$24 |
Look at rows one and six. Both are books somebody would be pleased to own. One returns $397 and one returns $23, and the $23 book is in far better condition. That gap is the entire argument for ranking before packing.
Where to draw the cut line
The cut line sits at zero expected net. Above it, the book pays for its own slot and leaves change. Below it, you're paying CGC to reduce your money. Simple enough — except the interesting books are the ones sitting within about $25 of the line, because those are the ones a half-grade miss flips.
Take the copper minor key at +$10. That's a GO on paper. Now assume it comes back at the bottom of its band instead of the top, so the slabbed comp is $80 rather than $105. Net becomes −$15. The book didn't change; your estimate did. Anything that thin isn't a decision, it's a coin flip with a $36 stake, and the honest label for it is too close to call.
So run the cut line twice. Once at your expected band, once one band lower. Books that clear both go in the box without further thought. Books that only clear the optimistic run are your swap candidates — the first things to drop when a better book turns up. The grading scale guide covers what actually separates adjacent grades, which is usually less than people assume, and the census population report tells you whether a high grade on that issue is rare or routine before you bet on the premium.
When padding to 25 still pays
Here's the case the cut line alone gets wrong. Say only nineteen of your books clear. You need six more to reach the minimum, and the next six all lose money individually. Do you pad, or do you send nineteen on a pricier tier?
It depends on how much the bulk tier saves across the books that do earn their slot. If the saving on nineteen good books outweighs the combined loss on six fillers, padding wins — the fillers are the price of the discount, not a mistake.
| Line | Box A | Box B |
|---|---|---|
| Books clearing the cut line | 19 | 12 |
| Tier saving per book vs next tier up | $12 | $12 |
| Total saved by qualifying for bulk | +$228 | +$144 |
| Filler slots needed to reach 25 | 6 | 13 |
| Combined loss on those fillers | −$106 | −$348 |
| Net effect of padding | +$122 | −$204 |
| Call | Pad it | Send fewer |
Box A pads and comes out ahead. Box B doesn't have enough good books to carry thirteen passengers, so it should submit twelve on a costlier tier and wait for the pile to grow. That's the rule in one line: pad while the tier saving across your winners beats the total loss on the fillers you'd add. Once you're reaching past the merely marginal books into genuine junk, the discount has stopped being a discount.
One more thing about padding. If you must add filler, add the filler that loses least — the −$7 book, not the −$24 book. Six carefully chosen passengers cost about half what six random ones do.
The books that aren't ready yet
A third verdict sits between GO and NO-GO, and it's the one that changes a bulk box the most: press first. Pressing takes out non-colour-breaking spine ticks, bends and waviness. On the right book it moves half a grade, occasionally a full one, and half a grade near a price cliff can be worth more than the rest of your box combined.
The test isn't whether the book has defects. It's whether the defects are the pressable kind and whether the grade bump crosses a price step. Pressing a common modern from 9.4 to 9.6 adds cost to a book that was already below the line. Pressing a key from 9.2 to 9.6 can double the slabbed comp. Our pressing guide covers which defects respond, and press and resubmit covers doing it to a book that's already slabbed.
Practically: pull the press-first books out of this box. Send them next time. A bulk submission is not the place to gamble on a press turning a marginal book into a good one, because you'll have paid the slot either way.
Building the box, in five moves
- Screen wide, not deep. Pull every plausible candidate first — forty, fifty books. Ranking thirty candidates for twenty-five slots gives you room to swap; ranking twenty-six gives you none.
- Get a raw and a slabbed comp for each. Two grades of slabbed comp, so you can see the price cliff. This is the slow part and it's the part that pays.
- Rank by expected net, then rank again one band lower. Books clearing both runs are locked in. Books clearing only one are your swaps.
- Check tier eligibility before you commit. The cheapest tiers cap declared value per book. A genuine key often can't ride along on the bulk rate, and mixing eras can push the whole box up a tier — see the tier and fee breakdown.
- Fill any remaining slots with the smallest losers. Only if the padding arithmetic above says the discount still covers them.
Then send it and forget it for six weeks. Turnaround runs around 45 days on standard tiers and the cheap tiers usually sit at the slower end, so plan the sale for after — the whole box comes back together, and one slow book holds up all twenty-five. Current queue behaviour is tracked on our turnaround page.
Who this doesn't help
If you're grading for certification rather than resale — insurance, an estate valuation, a personal collection you'll never sell — none of this applies. There's no spread to make, so the only question is which books you want protected, and the answer is whichever ones you care about.
It also won't help a dealer submitting hundreds of books a month. At that volume you've got your own comp data and your own sense of the cliffs, and a per-book check is friction you don't need. This is written for the person with one box, one shot at the minimum, and no way to eat six bad calls.
Questions bulk submitters ask
How many comics do you need for a CGC bulk submission?
CGC's cheapest per-book tier requires a bulk submission of 25 books minimum. Below that you're on a standard tier at a higher per-book rate. The minimum is what forces the selection question — you either find 25 books worth sending or you pay more per book on a shorter list.
Which comics are worth including in a bulk submission?
The ones where the slabbed comp beats the raw comp by more than the slot costs — roughly $27–45 in tier fees plus about $5 handling and a share of shipping. Rank every candidate by that number and cut where it turns negative. High grade on its own isn't a reason; a clean copy of a common book stays common in a slab.
Should I add filler books just to hit 25?
Only when the tier saving across the books that do earn their slot outweighs the combined loss on the fillers. Nineteen winners can usually carry six passengers. Twelve winners can't carry thirteen. If you have to pad, pad with the books that lose least, not the first ones you grab.
Can I mix vintage keys and moderns in one bulk submission?
Not always. The cheapest tiers cap declared value per book, so a high-value key usually has to go on its own pricier tier rather than riding the bulk rate. Check tier eligibility per book before you pack, because one ineligible book can force the whole submission onto a different schedule.
What does a bulk submission cost per book?
Tier fees run roughly $27–45 per book depending on declared value and era, plus about $5 handling per book. Bulk sits at the lower end of that band. Shipping both ways and return insurance are on top, though spread across 25 books the per-book shipping share is small — which is most of the saving.
Should I press books before a bulk submission?
Press the books where the defects are pressable and the grade bump crosses a price step. Pull those out of this box and send them next time rather than gambling a paid slot on the press working. Pressing does nothing for tears, stains, colour loss or spine splits.
Does a bulk submission take longer to come back?
Turnaround runs around 45 days on standard tiers and the cheapest tiers usually sit at the slower end of whatever the queue is doing. The whole submission returns together, so a single held-up book delays all 25. If you need to sell inside two months, that's an argument for selling raw.
Rank the pile before you pack it
Photograph each candidate and you'll get a grade band with a confidence level, the comps at that band, the correct tier, and a GO, NO-GO or PRESS FIRST with the expected net beside it. About 30 seconds a book — which is roughly the time it takes to put the wrong one in the box.
