Most Valuable Science Fiction Comic Books in 2026
In a world were we all have computers in our pockets and the world of knowledge at our fingertips, it's hard to properly appreciate the golden age of science fiction.
Science Fiction and comic books are well suited to one anotherThe relatively cheap format of comic books suits science fiction to a T.
Science fiction predates comics themselves, with plenty of pulp magazines and novels exploring the genre before the "birth" of comics in the Golden Age around 1935.
Some of the best-known and valuable sci-fi comic book series include:
- Mystery in Space
- Guardians of the Galaxy
- Space Adventures
- Avengers
- Weird Science/Fantasy
- Planet Comics
- Fantastic Four (their entire origin is sci-fi)
- Strange Adventures (notably those starring Adam Strange)
- X-Men
- Action Comics (some of the stories are pure science fiction)
- Wonder Woman
There is science fiction throughout most comic series. For example, Man-Wolf (Amazing Spider-Man #124 and #125) has a space origin story.

Most Valuable Science Fiction Comic Books
Planet Comics #1 (1940)
Rare first issue of sci-fi series
Lowest price $5,000
Average price $18,000
Record price $108,000
Muscular heroes, well-endowed and scantily-clad females and weird spaceships battle bug-eyed green monsters in Planet Comics.
This long-running series eventually died out when crime and horror comics overtook sci-fi as the most popular publications of the later Golden Age.
Fantastic Comics #3
Classic robot cover
Lowest price $30,000
Average price $90,000
Record price $243,000
Lou Fine created several so-called classic covers in the Golden Age, but this one is by far the most desirable -- and very rare -- sci-fi comic book.
Only 17 unrestored examples have been certified by CGC, but this number includes a CGC 9.4! When that is sold, a massive record will be set for this issue.
Startling Comics #49
Robot bondage cover
Lowest price $4,000
Average price $14,000
Record price $132,000
This is an absolute classic cover! Alex Schomburg created this insane robot carrying off a bound woman.
Action Comics #12
Zatara sci-fi cover
Lowest price $7,500
Average price $15,000
Record price $22,000
The non-Superman covers are less desirable from the early years of Action.
All Star Comics #13
Sci-Fi cover
Lowest price $200
Average price $500
Record price $2,280
Early in the Golden Age, sci-fi comic books often featured rockets and flying saucers. The Justice Society of America faced aliens in this early adventure.
Batman #41
1st Sci-Fi cover in Batman Comics
Lowest price $200
Average price $600
Record price $13,200
Little green men were another popular subject matter for vintage sci-fi covers.
Boy Commandos #36
ATOMobile Sci-Fi cover
Lowest price $50
Average price $200
Record price $3,120
One of the more off-beat titles in the Golden Age DC Comics stable. Cool future car and, honestly, is this really any more weird than the Cybertruck?
Space Adventures #12 (1954)
Classic cover by Ditko
Lowest price $500
Average price $4,000
Record price $36,000
Although Charlton is best-known for TV tie-in comics, they also published some memorable pre-Code comics, including this amazing issue. It features an insane sci-fi image by Steve Ditko.
This is the most valuable Charlton issue to sell so far.
Fantastic Four #2
1st Skrulls
Lowest price $500
Average price $3,000
Record price $90,000
The Skrulls (as seen in the Miss Marvel movie) are shapeshifting aliens who desire to take over Earth.
You could argue that all Fantastic Four comic books are science fiction comics!
Action Comics #242
1st Brainiac
Lowest price $400
Average price $5,000
Record price $34,000
Surely Brainiac is long overdue for an appearance in the soon to expand DCU?
This is one of the toughest Action Comics key issues, with a purple cover that shows a lot of wear.
Avengers #8
1st Kang the Conqueror
Lowest price $75
Average price $800
Record price $19,200
Kang is the villain from the MCU movie Ant-Man and the Wasp: Quantumania and Avengers: The Kang Dynasty, making this a major key issue.
Flash #139
1st Reverse Flash/Professor Zoom
Lowest price $90
Average price $750
Record price $8,400
Reverse Flash is a huge villain in the DCU, and this first appearance as Flash of the 25th century is very collectible.
Thor #165
Lowest price $50
Average price $150
Record price $25,000
This is the first true appearance of Adam Warlock (although Fantastic Four #67 has a similar claim). The Watcher's back story is retold in this issue.
Mystery in Space #75
First crossover appearance of JLA; 7th appearance in all
Lowest price $20
Average price $100
Record price $2,650
The first time the JLA appeared in a different title, and chronologically the story is before Justice League of America #4. An obscure issue from an obscure title, and under-valued in our opinion.
Mystery in Space #1
1st in series
Lowest price $150
Average price $1,250
Record price $10,200
This was the first issue in a long-running series, which crossed over to the Justice League of America in issue #75.
X-Men #107
First Starjammers
Lowest price $20
Average price $120
Recent 9.8 Sale $7000
Record price $12,000
Starjammers have a brief MCU footprint, and this issue has jumped in value since.
Amazing Adventures #1 (1950)
Ziff-Davis sci-fi comic
Lowest price $50
Average price $200
Record price $4,560
Back in the Golden Age, science fiction exploded in popularity. This painted cover is really detailed and imaginative and captures the spirit of the era of the pulp magazines which preceded comics. Surprisingly affordable in mid-grade.
Astonishing #3 (#1) (1951)
Scarce sci-fi comic book
Lowest price $200
Average price $400
Record price $2,160
What's really astonishing is that this comic hasn't broken five figures yet! It surely will when a nice copy comes to market. Quite a rare sci-fi comic book from 1951.
Journey into Unknown Worlds #37 (#2)
Planets collide cover story
Lowest price $100
Average price $450
Record price $2,630
A classic, beautifully coloured sci-fi comic book cover from 1951. This is issue #2 after the series was renamed at #36.

1st Judge Dredd
Lowest price $200
Average price $750
Record price $11,000
The first appearance of Judge Dredd makes this a classic UK science fiction comic book.
It's critically important to ensure that the free sticker sheet is included if you purchase a copy of this. Without it, the comic is considered incomplete. The sheets can sell for $200 on their own!
Space: 1999 #1 (1975)
1st Moonbase Alpha
Lowest price $5
Average price $20
Record price $120
Charlton Comics published this TV series spin-off. Like the show, it was short-lived, with just eight issues.
A-1 Comics #61 (Space Ace #5)
Space Ace cover
Lowest price $50
Average price $150
Record price $1,560
Not the first appearance of Space Ace; that was in Manhunt #1. Quite a rare comic, but not in great demand.
