FANTASTIC FOUR #100

Cover shows good color and gloss with no major creases visible, though there is mild surface wear and a slight softness at the corners typical of handling. Spine appears mostly tight with only minor stress lines, no significant ticks or color breaks visible in this photo. The book is in a protective sleeve, which limits full assessment of edges and corners; interior and back cover were not examined. Overall presentation suggests a mid-grade copy in the Fine range.

Fantastic Four #100 caps the Lee/Kirby collaboration that defined the series, published as a giant anniversary issue assembling a gauntlet of villains including the Mad Thinker, the Wizard, Klaw, and the Puppet Master's Awesome Android, alongside a Sub-Mariner appearance. It stands as Jack Kirby's last regular penciling job on the title he co-created before his departure from Marvel in 1970, making it a natural bookend to the King's foundational run rather than a first appearance or origin story. Stan Lee's script leans into the celebratory nature of the hundredth issue, tying together plot threads and villains from earlier in the run for a valedictory feel.

Market activity reflects a well-collected mid-Bronze Age anniversary book rather than a headline key: certified sales are broad and steady across the grade spectrum, with over 1,100 census copies and consistent demand from grade 4 through 9.4. Values climb gradually through the mid grades before a sharp premium appears at the 9.6 and especially 9.8 tier, where thin population and completionist demand from Kirby and Fantastic Four run-builders push prices well above the near-flat plateau seen in lower grades. This step-function pricing pattern, common to Bronze Age Marvel keys-adjacent issues, indicates the book's value is driven primarily by condition census placement rather than raw scarcity.

The book appeals most to Fantastic Four run collectors and Kirby completists filling out the artist's final Marvel output, rather than character-first-appearance investors. Lower and mid-grade raw copies trade as affordable reading copies with modest, stable demand, while true premium activity concentrates in the 9.6+ tier, where a limited high-grade population creates meaningful separation in value. Long-term, the issue should continue trading as a steady, moderate-demand anniversary book anchored by its historical role marking the end of the Lee-Kirby FF era.
