AVENGERS #28

Cover shows strong gloss and bright inks with only mild wear at the corners; a faint spine tick or two is visible along the spine edge but no major color breaks are apparent. Slight yellowing/toning is visible at the extreme edges consistent with age. There appears to be minor edge wear at the bottom right corner. The book is in a protective sleeve, which limits full assessment of surface and edge condition, and the interior and back cover were not assessed.

Avengers #28 (May 1966), written by Stan Lee with art by Don Heck and inks by Vince Colletta, concludes the "Road Back" arc in which Egghead recruits Power Man (Erik Josten) and introduces Jacques Duquesne, the Swordsman, as an infiltrator sent to undermine the team from within. The Swordsman's debut here established a morally ambiguous antagonist who would eventually reform, later becoming a member of the Guardians of the Galaxy and a recurring figure across Avengers continuity for decades. The issue is a product of the classic Lee-Heck creative run that defined the team's mid-1960s roster shakeups following the departure of the original founding members.

Market data shows a book with steady, broad collector demand typical of a recognized first appearance rather than a headline-grabbing grail. Mid-grade copies trade in the low-to-mid double digits, reflecting the large surviving population (nearly 900 census copies) and consistent but unspectacular turnover at those grades. The real value concentration sits at the top of the census: prices rise sharply from 9.4 to 9.6, and the scarcity of unblemished 9.8 copies (only two known, no confirmed sale price) points to a significant premium for a top-graded example, driven by census-completionist buyers and Silver Age Avengers key-issue collectors.

This book suits collectors building a Silver Age Avengers run or a first-appearance-focused villain/anti-hero collection, and it holds crossover appeal among Guardians of the Galaxy collectors given the Swordsman's later team role. Lower and mid-grade copies remain accessible entry points for readers and casual collectors, while investment-driven buyers concentrate on 9.4 and above, where population scarcity and cross-title demand support the sharpest price acceleration. Expect continued gradual appreciation rather than volatile spikes, consistent with a solid, well-recognized but second-tier Silver Age key.
