The book in question sold for a record-high $507,500 and was graded at 5.5 (FN-) by CGC (Certified Guaranty Company), the leading provider of grading services in the comics industry.
Superman #1, the first comic to feature just one superhero, collects Action Comics #1-#4 by Jerry Siegel and Joe Shuster. This copy sold for a price comparable to that of Batman #1 ($567,625) and Wonder Woman #1 ($291,100), the first solo titles featuring the two respective DC powerhouses.
However, the book doesn’t come close to touching any all-time records. A CGC 8.0 copy of Detective Comics #27, the first appearance of Batman, sold for just north of $1 million in 2010 while a copy of the most popular comic of all time — Action Comics #1 — sold for $3.2 million in 2014.
“I encourage owners of high dollar comic books to get in touch with me in order to get top dollar and realize the highest return on their investment. The market is strong, and collector-investors are clamoring for key and high-grade Golden, Silver and Bronze Age comic books. On the flip side, hobbyists seeking rare, high dollar books like this one may reach out to me for exclusive purchasing opportunities,” said Josh Nathanson, Founder and President of ComicLink in a press release. “I have assisted top buyers in acquiring the best comic books for their collections since 1996, and applying my market knowledge to help collectors invest strategically is something I still enjoy doing.”
