AVENGERS #191

Cover shows strong gloss and bright colors with sharp corners and no visible creases or color breaks. There is a small diagonal crease or stress line near the top right edge and slight edge wear at the bottom left corner. The book is in a protective sleeve, and interior/back cover were not assessed.

Avengers #191 (Jan. 1979, Marvel) arrives during the David Michelinie-scripted stretch of the series with John Byrne on pencils, a pairing that carried the title through the late 1970s before Byrne departed for X-Men and George Perez took over art chores. The issue is a mid-run chapter rather than a spotlighted milestone, featuring the Avengers roster of the period without a first appearance, death, or origin attached to it. Its interest lies chiefly in the creative team and the era, not in any singular story event.

Market activity is sparse: certified sales cluster at the top of the grading scale, with only a handful of transactions recorded across 9.2, 9.6, and 9.8, and no population reported at any grade. That pattern is consistent with a book that circulates mostly as long-box filler in raw form, only occasionally submitted for grading, with demand concentrated among Avengers Bronze Age runs and Byrne art completists. Prices step up sharply as grade climbs, reflecting genuine scarcity of pristine surviving copies rather than broad collector competition.

This is a book collected as part of a complete Avengers run or a Byrne bibliography rather than sought on its own merits. Raw copies in low and mid grades trade cheaply and are readily available, appealing mainly to readers and set-builders; the real premium sits with a clean CGC 9.8, where thin supply meets a small but persistent pool of grade-conscious buyers. Expect steady, unspectacular movement across lower grades and occasional spikes at the top end when a fresh high-grade copy surfaces.
