ACTION COMICS #662

Cover shows strong gloss and vibrant color with sharp corners visible in the photo; no major creases, tears, or stains are apparent. Slight edge wear is possible at the extreme corners but not clearly visible through the protective sleeve, and minor glare from the plastic bag obscures fine surface detail. Spine appears flat with no visible stress lines or color breaking. Interior and back cover were not assessed, so grade is conservative.

Action Comics #662 arrived in February 1991 as part of the "Krisis of the Krimson Kryptonite" storyline running through the Superman family of titles, a mid-arc chapter written by Roger Stern with art by Bob McLeod during the tightly coordinated editorial era overseen by Mike Carlin. The crossover saw Superman's powers destabilized by a corrupted form of red kryptonite, with Mister Mxyzptlk manipulating events behind the scenes, and the storyline tied into the broader continuity of the Superman titles at the close of the 1980s creative overhaul. The issue carries no first appearance, death, or origin content and is representative of the dense multi-title continuity that defined the Superman office in this period rather than a standalone landmark.

Market data for this issue is sparse, consistent with its status as a mid-run crossover chapter rather than a sought-after single issue. The handful of recorded certified sales cluster at modest prices even in high grade, reflecting a book that trades primarily as part of complete Superman crossover runs or long-box bulk lots rather than as an individually pursued key. Demand is driven almost entirely by completists assembling the "Krisis of the Krimson Kryptonite" storyline or full Action Comics volume 1 runs, with little independent collector pull for the issue on its own merits.

This is a book collectors acquire to fill a run rather than to chase in isolation, and it typically moves in bulk lots, dollar bins, or as an incidental inclusion in Superman crossover sets. Raw copies in low and mid grades remain inexpensive and plentiful, while high-grade certified examples see occasional interest from Superman-title completists and CGC registry builders, but pricing at the top end remains speculative given how few examples have been graded or sold. It is best positioned in a dealer archive as a supporting piece within a broader Superman Copper Age offering rather than as a headline item.
