ACTION COMICS #667

Cover shows sharp corners, strong glossy surface, and no visible spine stress or ticks in this photo. There is a small ink smudge/mark near the bottom left corner text area that should be noted, along with minor edge wear near the top corners. The book is in a protective sleeve which limits full assessment; back cover and interior pages were not evaluated.

Action Comics #667 arrived in July 1991, part of the long-running flagship Superman title during its late Copper Age stretch under writer Roger Stern, in the period leading up to the industry-reshaping "Death of Superman" storyline that would begin the following year. The issue reflects the standard Superman status quo of the early 1990s, with no first appearances, deaths, or landmark creative milestones attached to it, placing it squarely among the vast majority of Action Comics issues from this era that serve as connective tissue in the character's ongoing continuity rather than as collecting landmarks.

The certified population is small, with only a handful of CGC Universal copies on census and a thin sales record concentrated at the top of the grade scale. Pricing between the available data points is compressed, with a mid-9 grade and a pristine 9.8 separated by only about ten dollars, indicating limited grade-driven demand and a market where completionists and Superman-run collectors account for most activity rather than speculative key-issue buyers. There is no meaningful gap between raw and certified values at the low end, consistent with a book that trades near cover price in worn condition.

This issue is best understood as a title-run filler book: valuable to Superman completists assembling a full Action Comics run in high grade, but of little interest to buyers focused on first appearances or major creative milestones. Most transactions will occur in bulk lots or as incidental additions to larger Superman collections, with single-copy sales concentrated at the high end of the grade scale where a handful of 9.8 slabs command a modest premium over mid-grade raw copies. Long-term appreciation is unlikely absent a broader resurgence of interest in this specific run.
