Here is a result that looks like a data error and is not. A CGC 8.5 copy of Sub-Mariner Comics #1 reportedly brought $144,000 in September 2021. A CGC 9.0 of the same issue — a higher grade, a nicer comic — reportedly brought $84,000 two years earlier.
The 8.5 carried the San Francisco pedigree, a collection known for exceptional page quality. The 9.0 carried the Larson pedigree. Both are real pedigrees; the market does not weigh them equally.
A pedigree name on the label can outweigh a grade point, and on Timely books it regularly does.
Why page quality is worth more than a grade point here
The CGC grade measures structural condition — corners, spine, creases, completeness. Page quality is recorded separately, as a note: white, off-white, cream, tan, brittle.
On 1941 newsprint that note carries enormous weight, because the paper is the thing most likely to have failed. Two copies can grade identically and be completely different objects if one has supple cream pages and the other is browning at every edge and ready to chip.
A pedigree with a documented reputation for page quality tells a bidder, before they see the book, that the paper is likely to be good. On a wartime Timely that is worth paying for, and clearly worth more than half a grade point.
Both of those figures reach me secondhand, so I have kept them labeled. The pattern they describe is well established regardless.
The sales I can actually stand behind
| Grade | Result | Where and when |
|---|---|---|
| CGC 8.5, San Francisco pedigree | $144,000 (reported) | reportedly September 2021 |
| CGC 8.0 | $72,000 | Heritage Auctions, September 2024 |
| CGC 7.5 | $44,000 | ComicLink, September 2025 |
| CGC 6.5 | $33,608 | ComicConnect, March 2026 |
| CGC 9.0, Larson pedigree | $84,000 (reported) | reportedly 2019 |
| any condition | around $2,900 (reported, undated) | — |
Three sales I can actually stand behind now, and the mid-grade pair are still the ones most likely to describe your copy. A 7.5 at $44,000 and a 6.5 at $33,608, six months apart, is a clean and recent pair. One grade point, about ten thousand dollars, no pedigree on either label — though the 6.5 sold inside the Eric Groves Collection event at ComicConnect, which set records across the board.
The third sits above them: a plain CGC 8.0, no pedigree on the label, brought $72,000 at Heritage in September 2024. That is the first documented figure for a high-grade ordinary copy of this book, and it puts the pedigree results in proportion — the San Francisco 8.5 reportedly brought exactly twice as much, half a grade point higher. A year separates the 8.0 from the 7.5, and the step between them is bigger than the one below it — $28,000 for half a grade — which is what the top of a ladder usually looks like on a book this scarce.
That is the ladder to use. The pedigree results tell you what the ceiling looks like for exceptional copies; these three tell you what the market does for good ordinary ones.
The third of the big three
Timely launched three solo titles that collectors treat as a set: Captain America Comics #1, Human Torch #2, and this one. Namor had been running in Marvel Comics #1 since 1939; this is where he got his own book.
Collectors chasing the set create demand that does not depend on Namor’s profile at any given moment, which is useful because he has spent long stretches out of the public eye.
The run beyond #1 has value too — reported records of $50,400 on #13 and $40,800 on #16, both undated, which I mention only so you do not treat the later issues as filler. I will tell you whether the rest of the box is where the money actually is, because on Timely runs it often is.
What page quality actually means on a label
Since this whole page turns on page quality, here is what the terms mean, because they appear on every slab and most sellers never have them explained.
- White — essentially as printed. On a 1941 comic this is close to miraculous and usually indicates exceptional storage.
- Off-white — very slight aging. Still excellent for the period.
- Cream — visible aging, paper still supple. This is a good, normal result for a wartime book.
- Tan — noticeably darkened. Common, and priced accordingly.
- Brittle — the paper chips or cracks when flexed. This is a serious problem and it caps what a copy can bring regardless of how it looks.
The reason it moves money so much on Timely books specifically is that wartime paper stock was poor to begin with — the better grades went to the war effort — so the range of outcomes across surviving copies is unusually wide. Two comics that grade the same can sit several rungs apart on this scale.
When you photograph a copy for me, an edge-on shot showing the paper color is genuinely more useful than another angle on the cover.
Selling a Sub-Mariner Comics #1
- Note the page color honestly. Cream and supple is a different object from tan and brittle at the same grade, and on this book the difference is real money.
- Do not handle it more than you must. Wartime paper chips at the edges and every handling risks a new defect.
- Use the 8.0, 7.5 and 6.5 results, not the pedigree ones. Unless your copy has documented provenance, the pedigree sales are describing a different market.
- Keep the run together until it has been looked at. Later issues carry real value and get discarded by people sorting for the number one.
