Top Sub Mariner Comic Books in 2025
Most Valuable Sub Mariner Comic Books in 2025
Rooted in the Golden Age of Comics, Sub-Mariner has been part of the superhero landscape since the early 1940s.
Which are the most valuable Sub-Mariner comic books in today's market?Despite being part of the history of comic books, Namor has never quite made it to the A-list.
He has largely been a villain, sometimes in tandem with others such as Doctor Doom, sometimes as the main antagonist against the Fantastic Four.
You could make the argument that Namor is the Marvel equivalent of Aquaman.
He reappeared in the Silver Age in the early 1960s and for a while became a mainstay of Marvel Comics.

Most Valuable Sub Mariner Comic Books
Marvel Comics #1 (1939)
First ever Marvel comic book
Lowest price $120,000
Average price $300,000
Record price $2.42M
An exceptionally rare and critically important issue, the first ever Marvel comic, published during the Timely Comics era.
There are just 37 unrestored examples in the census! A further 33 restored examples are known.
Sub-Mariner Comics #1 (1941)
The first solo Timely Sub-Mariner comic book
Lowest price $7,000
Average price $30,000
Record price $144,000
The Sub-Mariner has been rebooted, most notably in Fantastic Four comic books, where he has teamed up with Doctor Doom to fight the FF.
The Golden Age version is a giant character who bears little resemblance to the Silver Age villain.
Young Men #24
Human Torch returns; "Cap" appearance
1st Grand Director
Lowest price $300
Average price $1,300
Record price $6,000
One of the most underrated key issues of the late Golden Age, the return of Human Torch also features Cap in the story.
This Captain America is not the one frozen in ice who was resurrected in Avengers #4.
This is a complicated continuity issue which was later "fixed" by writers claiming that Cap in this story was an imposter, or "Bad Cap".
Fantastic Four #4
1st Silver Age Sub-Mariner
Lowest price $700
Average price $2,500
Record price $81,000
Sub-Mariner is a bad guy who doesn't mind who he fights. He battles the Avengers in combination with the Hulk in Avengers #3, as well as on many other occasions.
Fantastic Four #6
Sub-Mariner and Doctor Doom team-up
Lowest price $200
Average price $1,000
Record price $60,000
This super-villain team-up is one of the earliest in the Marvel universe. Sub-Mariner first appears in the Silver Age in Fantastic Four #4.
Sub-Mariner #1 (1968)
1st solo comic; FF appearance
Lowest price $60
Average price $450
Record price $9,300
The Sub-Mariner is going to be a big part of the MCU in the next phase. His appearances have taken off in value in recent years after a long period of being mostly overlooked.
Iron Man and Sub-Mariner #1
Pre-dates Iron Man #1
Lowest price $40
Average price $300
Record price $40,000 (CGC 9.9);
$20,300 (CGC 9.8)
If you think this is a strange combination, then you're not alone (especially when you see Iron Man #54). This hit the newsstands before Iron Man #1.
Sub-Mariner #5
1st Tiger Shark
Lowest price $20
Average price $100
Record price $8,400
Tiger Shark is an important Sub-Mariner villain in Marvel Comics.
Sub-Mariner #8
Namor vs Thing battle

WHYITSIMPORTANT
Sub-Mariner #34

Record price $3,250
This is an important tryout issue for the Defenders.
Sub-Mariner #35
Hulk vs Thor vs Sub-Mariner
Lowest price $10
Average price $100
Record price $800
In the very early days of the Defenders, before they split off into their own issue, this fight between Thor and Hulk occurred.
Fantastic Four Annual #1
Very early Spider-Man appearance
Lowest price $75
Average price $400
Record price $40,800
Somewhat resembling the Mexican luche libre wrestler style art from the Avengers #11 appearance, this very popular early Marvel annual is either the 4th or 5th total appearance of Spider-Man.
Avengers #3
Hulk fights the Avengers
Lowest price $60
Average price $400
Record price $18,000
Incredible Hulk returns to fight the Avengers alongside Sub-Mariner.
Uncanny X-Men #6
Sub-Mariner crossover
Lowest price $120
Average price $500
Record price $40,800
A classic early X-Men comic featuring Namor in the cover story.
Strange Tales #125
Sub-Mariner cover story
Lowest price $20
Average price $120
Record price $3,000
Another classic Namor vs Thing cover.
Tales to Astonish #70
Hulk and Sub-Mariner double headers begin
Lowest price $15
Average price $100
Record price $2,400
While the title had been a double header before, this switch to Sub-Mariner reflected the lack of popularity of Giant-Man.
Tales to Astonish #82
Iron Man battles Sub-Mariner
Lowest price $15
Average price $80
Record price $2,600
A classic battle between the red and gold Iron Man and the underwater bad guy.

1st Abomination
Lowest price $20
Average price $100
Record price $19,200
The first cameo of Abomination is minor compared to the next issue, which is a full cover story.
Marvel Feature #1
1st Defenders appearance
Lowest price $20
Average price $100
Record price $9,000
Doctor Strange, Hulk and Sub-Mariner form the super-team Defenders in this issue, after several try-out and buildup stories in other titles.
Defenders #1
1st in dedicated series
Lowest price $25
Average price $100
Recent 9.8 Sale $2,350
Record price $18,300
No book illustrates the pandemic bubble bursting quite like Defenders #1. It's over 87 percent down from the all-time high! This is what all those NFT comic book owners have been feeling like for a while now... I guess it's good to be a skeptic sometimes.
Defenders #10
Thor vs Hulk Battle
Lowest price $10
Average price $60
Record price $1,000
Some match-ups are classic, including Thor vs Hulk, and this cover is one of the finest of the breed.
Invaders #1
Cap, Bucky, Human Torch, Toro and Sub-Mariner
Lowest price $10
Average price $90
Record price $1,300
The Invaders were one of Marvel's attempts to create a new super-team in the Bronze Age era.
