superman comic auction record heritage 2719637

A first-edition copy of "Superman No. 1" from 1939 sold for $9.12 million at Heritage Auctions on November 20, setting a new record for the most expensive comic book ever sold. The comic was discovered in a cardboard box in the attic of a Northern California home by three brothers after their mother's death, preserved in near-mint condition (graded 9 out of 10 by CGC). Alongside it, they found other valuable early comics, including a 1939 Action Comics featuring Zatara ($204,000) and a Superman-focused issue ($264,000).
