Due to the rise of Pop Art in the 1960s and the popularization of commercialized goods and illustration, there was a rise in the demand for nostalgic 1940s comic books throughout the later half of the 20th century. In his book, Comics Versus Art (2012), Canadian art educator and author Bart Beatty discusses why 1940s comic books had a resurgence in the 60s. He claims that 40s comics gained popularity again in the 60s for many reasons, including research and academic purposes, (both Pop Artists and colleges/universities studying technique and social attitudes in 40s comics) and also personal reasons, such as nostalgia (Beatty 153). Private collectors and companies dominated the comic book market throughout the 60s, 70s, and 80s. Private collectors and companies would buy comic books, determine their quality and condition, and assign them a grade. Based on this grade, they would then determine how much a comic is worth. Some collectors would only collect for monetary reasons, and many comic book enthusiasts would shame those people. 
              In the 1990s, the comic book market got so intense that New York City auction houses wanted in on the buying and selling of the most popular American comics. Famous art auction houses, such as Sotheby’s and Christie’s, started holding auctions for old famous and influential comic books. By the time the auction houses had started having comic book auctions, original comics from big names such as Marvel and D.C. Comics were worth a lot of money.
For example: In 1979, Marvel Comics #1 was worth roughly $13,000. In 2001, when sold by an auction house, the same comic was worth $350,000. Action Comics #1 (the first Superman comic book) sold for $4,200 in 1977. In 1995 it sold for $125,000, and in 2008, it sold for $475,000. Today, it is estimated to be worth an enormous $6 million. 
However, one must remember that even though comics were occupying the same space as modern art when being auctioned, they still weren’t being thought to be the same standard as traditional and modern art. During Sotheby’s 1991 comic book auction, they didn’t display the comics as art, as the books were wrapped in plastic and available for the public to handle. Even though comic books were considered to be extremely valuable, they were still not considered to be fine art.
