The first issues of both X-Men and Avengers sold for world record prices at an auction of high-grade Silver Age comics organised by Heritage Auctions on July 26.
The 1963 copy of X-Men no. 1 sold for $492,937.50, while the copy of Avengers no. 1 sold for $274,850, according to The Hollywood Reporter.
The X-Men no. 1 copy sold at the auction was one of only two surviving copies in near-pristine condition left in the world, scoring a CGC grade of 9.8 out of 10.
The sale price for the comic book more than doubled the previous record of $200,000. X-Men no. 1 now ranks as the second most valuable Silver Age Marvel comic after the first appearance of Spider-Man in Amazing Fantasy no. 15.
Meanwhile, Avengers no. 1 sold for $274,850 at the auction, slightly surpassing the previous record of $250,000. The copy sold had a grade of 9.6, making it one of the three highest-graded copies left in existence.
The results of this latest auction continued a record run for collectible comics recently that has seen prices soar. In November 2011, a 1938 copy of Action Comics no. 1 sold for a world record $2.1 million, while earlier this year a copy of Iron Man’s first appearance sold for $375,000.
Silver Age Marvels in particular have been reaping the benefits of rising comic book prices. In the last two years, the first appearances of the X-Men, Spider-Man, Avengers, Iron Man, Thor and the modern Captain America have all sold for world record prices.
