FANTASTIC FOUR #140

Cover shows strong gloss and vibrant color with sharp corners and no visible creases or spine stress lines. Slight edge wear is visible at the top corners, and the book is currently housed in a protective sleeve which limits full assessment of edges. No tears, stains, or color breaks are apparent on the front cover; interior pages and back cover were not assessed.

Fantastic Four #140 (November 1973) arrived during Gerry Conway's tenure as writer, with pencils by Rich Buckler, capping the multi-issue Overmind storyline that had run through the preceding issues. The book folds in a guest appearance by the Inhumans, pitting Marvel's First Family against a cosmic-level telepathic threat in a story that reflects the more sprawling, crossover-heavy plotting typical of Marvel's early Bronze Age. It carries no first appearance, death, or origin of lasting significance, placing it squarely among the well-regarded but non-key issues of Lee/Kirby's successor era on the title.

Market data shows a large certified population, with 286 copies graded and 34 already at the 9.8 tier, indicating steady collector interest but no scarcity premium driving speculative demand. Pricing across the curve is gradual through the mid grades before climbing sharply at 9.6 and 9.8, the classic pattern for a common, well-preserved Bronze Age superhero comic where high-grade survival is the primary value driver rather than any narrative significance. Recent sales at 9.6 and 9.8 show modest but real premiums, consistent with continued demand from Fantastic Four run collectors rather than key-issue speculators.

This issue suits collectors assembling a complete run of Conway/Buckler-era Fantastic Four or Inhumans crossover appearances rather than investors chasing a marquee key. Raw copies in low and mid grade trade as inexpensive run-fillers, while CGC 9.8 slabs command a real but modest premium reflecting quality over rarity. Expect steady, unspectacular movement across grades, with the top census tier as the only meaningfully active price point.
