ADVENTURE COMICS #347

Image is rotated 180 degrees (upside down); grading assessed with that corrected orientation in mind. Visible defects include heavy corner wear and rounding at the top-left and bottom corners, multiple small chips and tears along the left edge, and general edge wear consistent with handling. There is noticeable spine stress and the cover shows some surface wear/soiling in the purple background areas. Interior and back cover were not assessed.

Adventure Comics #347 arrived in August 1966 as part of DC's long-running Legion of Super-Heroes feature, which had taken over the book's headline slot from Superboy earlier in the decade. The issue is best known among Silver Age enthusiasts as part of the earliest stretch of scripts credited to Jim Shooter, who began writing the Legion at just fourteen years old with Adventure Comics #346 the prior month; #347 continues that run with art by Curt Swan and George Klein, the definitive DC art team of the period. While not tied to a first appearance or origin story, the issue holds a notable place in comics history as an early professional credit for one of the medium's most influential future writers and editors.

Market data reflects a book that trades as a solid mid-tier Silver Age DC title rather than a marquee key. Certified sales cluster modestly in the $44–$55 range across VF to VF+ grades, with a thin but steady census spread across nearly every grade tier up through 9.6, and only a single unpopulated slot at 9.8. Demand is driven primarily by Legion of Super-Heroes completists and Jim Shooter collectors rather than by crossover interest from mainstream superhero buyers, giving the book a narrower but consistent collector base.

This is a book that moves steadily in raw form among Silver Age DC and Legion runs, typically picked up as part of building a complete Adventure Comics or Legion of Super-Heroes set rather than as a standalone target. High-grade certified copies see occasional premium interest from Shooter-run specialists and registry builders chasing the unpopulated 9.8 slot, but overall the issue remains an affordable, accessible entry point for Silver Age DC collecting rather than an investment-grade key.
