In 1962, comic books cost just a few cents, but, now, comics like Amazing Fantasy #15, a Spider-Man comic, costs millions if it is in mint condition. Marvel Comics’ #15 was a hit because it introduced Peter Park as your friendly neighborhood Spider-Man in August of 1962. One comic book website called this a “key issue comic” that is the “most famous comic book” of all time.

Amazing Fantasy #15 isn’t easy to find, if it’s an original. Decades have passed, and comic books weren’t printed on paper meant to last this long. Spider-Man collectors are willing to shell out millions for this piece of Peter Parker history.
