ACTION COMICS #668

Cover shows strong gloss and sharp corners with no visible creases or color breaks; spine appears tight with no stress lines visible in this photo. The book is protected in a plastic sleeve which limits full assessment of surface texture and edges. No significant defects such as staining, fading, or writing are visible on the front cover. Interior pages and back cover were not assessed, and slight glare from the sleeve may obscure minor surface flaws.

Action Comics #668 arrived in August 1991 during the tightly plotted Roger Stern era of the Superman line, a period defined by ensemble Metropolis storytelling, the Luthor corporate intrigue subplot, and steady buildup toward the sweeping crossovers that would follow in 1992. The issue reflects the workmanlike, densely scripted house style of the time, with Bob McLeod's pencils giving the book a clean, traditional superhero look typical of the late Copper Age Superman titles.

Market data for this issue is sparse, consistent with its status as a mid-run, non-key chapter rather than a spotlight issue. The handful of recorded certified sales cluster at modest prices even in top grade, with no meaningful gap between raw and slabbed values outside the 9.8 tier. Demand is driven almost entirely by Superman-title completists and Copper Age Action Comics run-builders rather than by any first appearance, death, or landmark event tied to this specific issue.

This is a book that trades as bulk-to-modest-value stock: inexpensive in low and mid raw grades, with value concentrated almost exclusively in true Gem Mint or near-Gem certified copies where scarcity of high-grade newsstand submissions creates a small premium. It suits collectors assembling a complete run of the Stern/McLeod Action Comics rather than key-issue investors, and pricing across grades should be expected to stay flat until a 9.8 or better copy re-establishes a fresh high-grade benchmark.
