Three Brothers Found a 1939 Copy of 'Superman No. 1' in Their Mother's Attic. It Just Became the Most Expensive Comic Book Ever Sold
The comic’s near-mint 9/10 grade and preservation in the Bay Area climate helped it sell for $9.12 million, setting a new record at auction.
- Last Thursday, Heritage Auctions in Dallas sold a Superman No. 1 comic for $9.12 million to an anonymous collector, discovered last Christmas by three brothers in their late mother's San Francisco attic.
- While preparing their late mother's house for sale, the brothers uncovered the comic last year in a box of old newspapers in the San Francisco attic, where she had bought it in 1939 when she was 9.0.
- Certified Guaranty Company graded the comic CGC 9.0, and Lon Allen inspected it, noting the near-mint physical condition with an intact spine, crisp corners, and vivid colors.
- The sale made it the most expensive comic book ever auctioned, and the three brothers remain anonymous amid their newfound fortune, per Heritage Auctions and the Associated Press.
- Market context shows earlier records at $5.3 million in 2022 and $6 million in 2024, while collectors noted the Bay Area climate preserved an attic collection with five early Action Comics.
