FANTASTIC FOUR #55

Cover shows notable spine stress with a vertical crease/split visible along the left spine edge and some wear at the top spine area; corners show mild blunting, especially top right near the Comics Code stamp. There's a diagonal crease running through the upper right quadrant of the cover and some minor surface wear/soiling scattered across the cover. The book is in a protective sleeve, which limits full assessment of edges; interior and back cover were not assessed.

Fantastic Four #55 (Marvel, October 1966) delivers "When Strikes the Silver Surfer!", the story in which Doctor Doom lures the Surfer to Earth and strips him of the power cosmic, turning his own board and abilities against him. Written by Stan Lee and drawn by Jack Kirby with inks by Joe Sinnott, the issue arrives just months after the Surfer's introduction in the Galactus trilogy and stands as one of the character's most consequential early outings, pitting Marvel's two most formidable antagonist-adjacent figures against each other. The cover, depicting Doom astride the cosmic-powered surfboard, is widely regarded as one of Kirby's strongest Fantastic Four images of the mid-1960s.

Market data shows a broad certified population exceeding 2,300 Universal copies, reflecting a title that was well distributed and has been consistently collected for decades. Pricing steps up sharply above 9.0, with 9.4 copies trading near $2,250 and recent 90-day activity pushing higher, indicating renewed high-grade demand. Sub-9.0 grades trade in a tight, shallow band from roughly $35 to $150, characteristic of a book valued primarily for its story and cover rather than any first-appearance premium, with value concentrated at the top of the grade curve rather than distributed evenly across the range.

The book suits Silver Surfer and Doctor Doom collectors, Kirby cover specialists, and Fantastic Four run-builders rather than pure first-appearance investors. Lower and mid grades move steadily as affordable reading and run-filling copies, priced for accessibility rather than scarcity. Top-end 9.6 and 9.8 copies are genuinely scarce relative to demand and command outsized premiums when they surface, driven by cover appeal and the small certified population at the summit of the grade curve rather than by key-issue status alone.
