Comics: Why keys are more sought after the first issues
Having a comic book where a beloved hero first appears is a historical moment, more than just paper and ink. This issue marks the beginning of a cultural legacy, and collectors often prize it over the character's first comic book solo title. One of the most iconic and clear examples is Spider-Man. His debut in Amazing Fantasy #15 (1962) is valued above his first appearance in The Amazing Spider-Man #1 (1963).
Although his solo adventures started in The Amazing Spider-Man #1 and helped cement the superhero in the Marvel universe, it built upon events from Amazing Fantasy #15.
His debut in 1962 was a test run; writers were taking a gamble, and publishers had no idea whether the new hero would catch on. Unsure of its success, Marvel printed relatively few copies of the comics. Decades later, the scarcity of surviving high-grade examples makes this issue especially desirable to collectors.
