An attic discovery in San Francisco has rewritten the history of comic collecting. A rare first edition of Superman No. 1, salvaged from a cardboard box beneath layers of newspapers and cobwebs in their late mother’s attic, has sold for a record $9.12 million at a Texas auction, making it the most expensive comic ever sold. Heritage Auctions, a Dallas-based firm, announced the sale, eclipsing last year’s landmark $6 million record set by Action Comics No. 1, which also featured the Man of Steel on its cover.
Originally published in 1939 by Detective Comics Inc., Superman No. 1 is one of a small number of copies still in existence. The 500,000 copies printed decades ago left only a handful today. The copy sold was graded 9.0 by CGC, indicating minimal wear and top-tier preservation. Remarkably, the cool Northern California climate helped keep this fragile treasure intact in the attic until its discovery.
Experts traced the edition through a tiny in-house advertisement within the comic that identifies it as a first edition. The copy’s sturdy spine and vibrant colors likely owe to the attic’s dry air and careful handling by the original owner’s family. The three brothers who found the comic, aged in their 50s and 60s, preferred to remain unnamed, emphasizing that this story goes beyond a simple sale.
“This isn’t simply a story about old paper and ink. This is a testament to memory, family and the unexpected ways the past finds its way back to us,” one brother said in a statement released by Heritage Auctions. Lon Allen, vice president of comics at Heritage, added that the discovery represented every factor a collector could want rolled into one—the right copy, the right condition, and the right provenance.
The combination of its 1939 debut, the enormous print run of 500,000, and today’s estimate of fewer than 500 surviving copies creates a rarity that few items in popular culture can rival. A high CGC grade of 9.0, coupled with a pristine spine and vivid colors, elevates this copy above most others found in collections or auctions. Inside, a small, in-house advertisement helped experts confirm it as part of the first edition slate of 500,000 copies.
