About the character
The Mad Titan, obsessed with death and the annihilation of half all life, became Marvel's most fearsome cosmic villain. First appeared in Iron Man #55, created by Jim Starlin — now one of the best-known comic book characters in the world.
What is a first appearance worth?
Iron Man #55 has solid collector demand. A presentable raw copy in the UK typically attracts an offer in the low to mid three figures; high-grade or CGC-slabbed examples can push into four figures. Restored copies are worth less but still very much wanted — we buy across all grades and conditions.
