MARVEL TEAM-UP #100

Cover shows strong gloss and vibrant colors with sharp corners and a tight spine; a small crease or spine tick is visible near the mid-spine area and there's minor edge wear at the bottom left near the barcode. No major creases, tears, or color breaks are evident, though slight surface waviness suggests light handling. Interior and back cover were not assessed, so grade is based solely on the visible front cover.

Marvel Team-Up #100, cover-dated December 1980, is the milestone hundredth issue of the long-running Spider-Man team-up title, scripted by Chris Claremont during his tenure on the book. Rather than the usual single guest star, the issue assembles a large cast of Marvel heroes to confront Doctor Doom, making it a celebratory bookend to the series' first century of issues and a snapshot of the early-1980s Marvel Universe at the height of Claremont's influence across the line.

Market data shows a typical Bronze Age demand curve for a non-key anniversary issue: raw and low-grade copies carry only nominal value, mid-grade raw copies trade modestly above melt, and value climbs sharply only at the top of the certified population, where CGC 9.8 copies have realized figures well above the 9.6 and 9.4 tiers on a handful of recorded sales. This pattern reflects a book that was heavily read and handled on newsstands rather than speculated upon, so high-grade survivors are scarce relative to demand from Spider-Man and team-up completists.

The issue is best understood as a collectible for series and character completists rather than a speculative key; it fills a milestone-numbering niche in run collections and appeals to Claremont-era Marvel readers. Expect low- and mid-grade raw copies to move steadily but cheaply through dealer boxes and online bulk lots, while CGC 9.8 slabs command a real premium and trade infrequently, driven by the thin high-grade population rather than any first-appearance or landmark-art status.
