FANTASTIC FOUR #45

This is the first appearance of the Inhumans, a key Silver Age issue. Cover shows moderate wear consistent with a mid-grade copy: visible vertical creasing and diagonal stress lines across the upper right and center of the cover (likely reflections/creases in the protective sleeve), a small chip/wear at the top left corner, and general softening at the corners. Spine appears to have some minor stress but no major rolls visible; slight color rubbing along the left edge margin near the Thing box art. The book is in a protective sleeve which obscures some fine detail, and the back cover and interior pages were not assessed.

Fantastic Four #45 (December 1966) is one of the defining Silver Age Marvel issues, delivering the first full appearance of the Inhumans — Black Bolt, Medusa, Karnak, Gorgon, Triton, and Crystal — after a partial tease in the preceding issue. Scripted by Stan Lee with pencils by Jack Kirby and inks by Joe Sinnott, the issue continues the Kirby/Lee run widely regarded as the artistic and narrative peak of Fantastic Four, embedding a new corner of the Marvel Universe that would recur for decades in both comics and adaptations. The introduction of this royal family of "Inhumans" also carried thematic weight uncommon for the period, folding questions of isolation and hidden identity into the team's ongoing conflict with the Fantastic Four.

Market data shows steady, broad collector participation across the full grade spectrum, with over 3,900 Universal copies on census against roughly 4,400 total graded — evidence of a book that has been aggressively pursued and submitted for decades rather than a sleeper title. Pricing rises sharply above the 8.0 range, with the jump from 9.2 to 9.4 alone reflecting nearly a 30% premium, a pattern typical of key Silver Age issues where high-grade survivors are scarce relative to demand. The complete absence of recorded sales at 9.6 or 9.8, despite a handful of certified copies existing, points to holders sitting on top-census examples rather than any lack of interest.

This is a book pursued at every collecting level: entry-grade copies satisfy readers building a complete Lee/Kirby FF run affordably, while mid-grade copies remain a staple of Silver Age key want-lists. At the top of the census, scarcity of both supply and sales data suggests any 9.8 that surfaces publicly would likely set a new benchmark rather than simply track the existing curve, making it a target primarily for advanced Marvel Silver Age and Inhumans specialists rather than general-interest buyers.
