‘Amazing Fantasy’ #15
“Amazing Fantasy” #15 is both rare and valuable. The final issue of a failing magazine (previously titled “Amazing Adult Fantasy”) publishers never anticipated this comic becoming a collector’s item. Writer Stan Lee used the dying book as an opportunity to publish a story he’d been working on about a tragically flawed hero named Spider-Man, and once this character took the world by storm, the issue became the ultimate Marvel collector’s piece. In 2016, a copy sold for $454,100.
