ADVENTURE COMICS #322

The cover shows moderate wear consistent with a well-read Silver Age book: rounded and slightly frayed corners, visible spine stress lines with minor color break, and light surface creasing across the lower third. There is some edge wear along the top and right border with minor chipping, and the paper shows typical age-related toning rather than bright white. No tears or writing are visible, but the interior and back cover were not assessed in this photo.

Adventure Comics #322 arrived in the summer of 1964 as part of the title's dual-feature run pairing the Legion of Super-Heroes with backup Supergirl stories, a format that defined the book's mid-1960s identity. Scripted and drawn by the era's regular Superman-family creative teams, including contributions typically associated with Jerry Siegel and Jim Mooney, the issue reflects DC's steady expansion of its 30th-century teen-hero concept alongside the Girl of Steel's own supporting continuity. It is not tied to a first appearance, death, or origin story, and its cover, while representative of the period's clean superhero house style, has not entered the ranks of widely cited classic covers.

Market data shows a typical long-run Silver Age curve: modest raw-copy activity in the lower grades giving way to a sharp rise above 8.5 as certified population thins out. Demand is driven primarily by Legion of Super-Heroes completists and Supergirl collectors filling out Adventure Comics runs, rather than by speculative key-issue buying. Sales at 9.0 and above show clear scarcity pricing, with very few copies certified near the top of the grade scale and essentially no recorded 9.8 transactions, indicating that the highest grades trade infrequently and are priced more on rarity than on documented sale history.

This issue suits collectors building a complete Adventure Comics Legion/Supergirl run rather than those chasing standalone investment-grade key books. Raw copies in low and mid grade move steadily but without urgency, priced for shelf-filling rather than centerpiece status. High-grade certified copies, by contrast, command a real premium purely on condition scarcity, making a 9.8 a notable find for census-driven buyers even though the book itself carries no landmark first-appearance pedigree.
