THE UNCANNY X-MEN #276

Cover shows strong gloss and vivid colors with sharp corners and no visible creases or tears. There is minor surface waviness/rippling across the cover, likely from the protective sleeve or slight handling, and a faint sliver of white showing at the top edge near the price box suggesting light spine stress. No color breaks, stains, or writing are visible. The book is in a protective sleeve which obscures fine detail; interior and back cover were not assessed.

The Uncanny X-Men #276 (May 1991) arrived during the concluding chapters of the Muir Island Saga, the storyline that saw the X-Men and X-Factor team up against the Shadow King on Muir Island. Written by Chris Claremont in the final stretch of his historic run on the title, with art from Whilce Portacio, the issue is a representative chapter of one of the longest and most consequential creative tenures in mainstream superhero comics rather than a stand-alone landmark. It features the expanded roster typical of the era, including Wolverine, Storm, Rogue, Gambit, and Psylocke, alongside the Shadow King as the arc's antagonist.

Market data shows a typical Copper Age distribution curve: value is negligible in low and mid raw grades, with meaningful appreciation concentrated almost entirely at the CGC 9.8 tier, where a deep and continuing sales record supports a stable price point in the low nineties. This pattern reflects the issue's high print run and broad availability in the certified population, which keeps raw-copy demand modest while collectors chasing complete-run sets or gem-mint census rankings sustain steady 9.8 activity. There is no first appearance, death, or other landmark event driving cross-collector demand beyond the Claremont-run completist base.

This issue trades primarily as a build-block for X-Men run collectors and Claremont-era completists rather than as an investment-grade key. Raw copies in low and mid grades are inexpensive and plentiful, making them accessible entry points for readers assembling the full Muir Island Saga arc, while the CGC 9.8 market caters to census-conscious collectors seeking top-of-the-population copies. Expect long-term price stability rather than significant appreciation, with demand tied closely to broader X-Men Copper Age interest.
