ADVENTURE COMICS #328

Cover image is fully upside down in this photo (rotation applied in metadata). Colors remain bright with good gloss retention, and the cover art shows no major creases or tears. Some mild wear is visible along the top edge and corners, with slight softening at the corner tips consistent with handling; a faint vertical line near the spine area may indicate minor stress but no obvious color break is visible. Interior pages and back cover were not assessed in this photo, so grade is based solely on visible front cover condition.

Adventure Comics #328 arrived in early 1965 during the run in which the Legion of Super-Heroes had taken over the lead feature from Superboy, part of DC's expansion of its 30th-century team concept that began gaining serious traction after Adventure Comics #247 introduced the group. By this point the series was a steady vehicle for scripter Edmond Hamilton and penciler John Forte, with Curt Swan supplying cover work typical of the period's clean house style. The issue is a representative entry in the Legion's foundational run rather than a first appearance or origin story, reflecting the team-driven, science-fiction-inflected superhero storytelling that defined the title through the mid-1960s.

Market data shows a typical Silver Age back-issue curve: mid-grade copies trade in the mid-forty-dollar range with little differentiation between 5.0 and 6.0, while values climb steeply above 8.5 as the surviving population thins. Census figures show reasonable representation through 9.0-9.2 but a sharp drop-off at 9.6 and above, with only a handful of copies graded that high and essentially no completed high-grade sales to anchor pricing precisely. Demand is driven primarily by Legion of Super-Heroes completists and Silver Age DC collectors building the Adventure Comics run rather than by crossover interest from outside the franchise.

This is a book that moves steadily rather than spectacularly: raw low- and mid-grade copies are affordable entry points for readers assembling a run, while true high-grade submissions are scarce enough that a well-preserved 9.6 or 9.8 would likely draw competitive bidding among the small pool of Legion specialists and census-chasers. It is best positioned in a dealer catalog as a solid supporting piece in a Silver Age DC or Legion of Super-Heroes collection rather than as a standalone investment-grade key.
