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 Roger Stern's tenure as writer on the Superman titles, with art by Bob McLeod, part of the tightly coordinated multi-book Superman continuity that defined the line in this period. The issue is a standard chapter entry rather than a landmark installment, offering no first appearance, origin, or creative milestone that would elevate it beyond its place in the ongoing narrative.

Market data for this issue is sparse, reflecting its status as a middle-of-the-run Copper Age book rather than a sought-after key. The CGC census lists only a handful of certified copies across all grades, with the sole 9.8 example anchored by a small number of recorded sales at a modest price point. Raw copies in low and mid grades see little organized market activity, trading instead within the broader bulk-longbox economy of late Bronze/Copper Age Superman titles.

This issue holds appeal primarily for Superman completists assembling a full run of the Stern/McLeod era or newsstand-format specialists pursuing distribution variants, rather than for investment-driven buyers. Across grades, the book trades as a low-cost commons title: raw copies remain widely available and inexpensively priced, while the rare 9.8 slab commands a premium disproportionate to the book's content, driven almost entirely by certified scarcity rather than narrative significance.
