David Gonzalez recently unearthed a copy of Superman #4 from the spring of 1940, ComicConnect.com COO Vincent Zurzolo told The Huffington Post on Friday. The comic could be worth between $500 and $5,000, Zurzolo estimates.

"It's amazing to me that he's still finding stuff," said Zurzolo, who has been in touch with Gonzalez since ComicConnect hosted the bidding for the first find.

Gonzalez previously told ABC News that he had come upon another antique issuethat featured Superman fighting dinosaurs, but he had yet to identify it. Zurzolo explained there was a delay because Gonzalez took some time to locate the cover.

The front of Superman #4 shows Superman holding up collapsing columns with Lex Luthor in the foreground. In the story, Superman battles a pterodactyl reproduced in Luthor's lab, according to Comic Book Religion.
