AVENGERS #23

Cover shows overall wear typical of a Silver Age book: moderate spine stress lines and slight whitening along the spine, mild edge wear at corners with minor blunting, and some surface scuffing/scratches visible especially in the dark background area. Colors remain fairly bright with no major color breaks, tears, or missing pieces noted. The book is in a protective sleeve, so glare partially obscures fine surface detail; interior pages and back cover were not assessed.

Avengers #23, cover-dated December 1965, is a mid-run Silver Age issue scripted by Stan Lee with art by Don Heck, part of the stretch following the team's famous 1965 roster shakeup that introduced Hawkeye, Quicksilver, and the Scarlet Witch alongside holdover heavyweight Giant-Man and the Wasp. The story, "Enter… The Executioner!", brings the Enchantress and the Executioner into direct conflict with the reconstituted team and features the undoing of Power Man (Erik Josten), the enhanced-strength adversary introduced two issues earlier. It sits within a well-remembered narrative arc but does not carry a first-appearance or origin distinction of its own.

The GoCollect certified population is large, with 934 Universal copies recorded of 998 total graded, reflecting steady collector demand for the early Lee/Heck Avengers run rather than scarcity-driven pricing. Values rise gradually through the mid grades before accelerating sharply above 9.0, a pattern typical of Silver Age superhero books where survivorship in high grade is thin relative to demand from series and run collectors. The near-total absence of sales or census data at 9.8 underscores how few copies have ever approached that grade, and the premium buyers place on the handful that exist far outstrips the linear trend seen through 9.0-9.6.

This is a book primarily sought by Avengers run-builders and Silver Age Marvel generalists rather than character-first-appearance speculators, so demand is steady rather than spiking. Raw copies in low and mid grade trade as affordable reading/filler copies for those assembling the 1965-66 issues, while true gem-quality certified copies command outsized premiums driven almost entirely by their rarity rather than storyline importance. Expect the book to remain a stable, modestly appreciating title rather than one prone to sharp market swings.
