CAPTAIN AMERICA #339

Cover shows sharp corners, strong gloss, and bright unfaded colors with a well-centered print. Spine appears tight with no visible stress lines or ticks in this image. No creases, tears, or stains are visible on the front cover; the book is in a protective sleeve which limits full assessment of edges. Interior pages and back cover were not assessed.

Captain America #339 arrived in March 1987 as part of the long, steady Mark Gruenwald stretch on the title, a run defined less by single blockbuster issues than by its sustained plotting of Cap's supporting cast, rogues, and slow-building character arcs. This issue sits within that middle stretch of Gruenwald's tenure, contributing to the ongoing narrative machinery of the series rather than introducing a character, origin, or death that price guides or collectors point to as a turning point. It is a representative artifact of Marvel's direct-market Copper Age output: consistent creative team, workmanlike production, and a readership built on series loyalty rather than speculation.

The certified population data reflects exactly this profile. Census numbers are modest and sales activity is thin across nearly every grade, with only a single verified transaction recorded at the low end of high grade. That scarcity of trades is itself telling: this is a book collectors hold as part of a run rather than chase individually, so pricing data is sparse and the market is thin at every tier, including the top of the census.

Demand for Captain America #339 comes primarily from Captain America run collectors filling out the Gruenwald years and from bulk Copper Age buyers rather than from key-issue investors. Raw copies in low and mid grade trade cheaply and are readily available; a Universal 9.8 commands a real premium simply because so few copies have been submitted and graded that high, not because of any recognized significance. This is a book for completists building the full run rather than a target for standalone acquisition.
