Collecting comic books is a popular hobby, and some of these comics can be worth a lot of money. From Superman and Batman to Marvel and DC classics, there are many comics that can cost hundreds of thousands or even millions of dollars at auction. All-Star Comics 3, for example, is always a valuable book due to its first appearance of the first superhero team known as the JSA. Ultra-Humanite is the world's first comic book supervillain, and his comic is also worth a lot.
The market for comics is unpredictable, and some books skyrocket in value while others crumble. Wonder Woman's first line of comics was released in 1942, shortly after the United States entered World War II, and it remains a valuable book with high ratings that can rival some of the main comics from the Golden Age. Steve Ditko and Stan Lee's 1962 comic features the first appearance of Spider-Man. When looking for valuable comics, it's best to look for books from the 70s or earlier.
Superman 1 (out of 193) is currently ranked number 1 in the best-selling comic of all time with a recent private sale (confirmed by CGC). The comic has skyrocketed in value due to Wonder Woman's revival in film and popular culture. DC publisher Harry Donenfeld was worried that a competing publisher would steal the title of Action Comics in 1937, so he sent it to the United States. It's possible that there are even more expensive comics waiting to be discovered.
The Fantastic Four adventure was created by Stan Lee and Jack Kirby in 1961, and having a comic with a low number is another good indicator that it's worth something. This list reduces hassle and provides you with the 50 most valuable comics ever printed. The price can be misleading because the 5.0 (listed below) that sold for 108,000 had slightly brittle pages, which is always a big negative for any comic.
