A piece of superhero history has soared to unprecedented heights after an original Superman comic, discovered unexpectedly in an attic, shattered the world record for the most expensive comic book ever sold. The rare copy of Action Comics No. 1—the 1938 issue that marked the first appearance of Superman—was auctioned for a staggering $9.12 million, setting a new benchmark in the world of collectibles.
The comic was found inside an old chest while a family was cleaning out a relative’s home. Shocked by the discovery, they contacted comic preservation experts, who confirmed the issue was in remarkably strong condition, especially considering its age. Graded as one of the best-preserved copies ever seen, its historical and cultural value sent collectors into a bidding frenzy.
Auction officials described the sale as “monumental,” noting that the price reflects not just rarity but the global impact of Superman as a pop-culture icon. This particular issue is widely regarded as the birth of the superhero genre, making it arguably the most important comic book ever printed.
“This sale proves that superheroes aren’t just beloved—they’re timeless,” said a spokesperson for the auction house. “Finding a copy like this in an attic is the kind of discovery collectors dream about.”
Experts say the new record will likely influence the value of vintage comics worldwide, strengthening interest in early-era superhero issues from DC and Marvel. For the family who made the discovery, the sale is nothing short of life-changing.
From dust-covered attic storage to a multimillion-dollar global spotlight, the comic’s journey is as extraordinary as the hero who debuted in its pages—showing once again that Superman continues to break boundaries nearly nine decades after his creation.
