CAPTAIN AMERICA #340

Cover shown in protective sleeve appears glossy with strong, bright colors and no visible spine ticks or stress lines from this angle. Corners appear sharp with no visible blunting or creasing, and the black background is largely clean with no scuffs or scratches evident. A faint diagonal crease/wrinkle is visible near the bottom left corner near the Spider-Man logo box, which may be a minor handling mark or a bag reflection. Interior pages and back cover were not visible for assessment, so grade is based solely on the front cover's apparent high-gloss, well-preserved condition.

Captain America #340 arrived in April 1988 during Mark Gruenwald's lengthy tenure as writer, a stretch of the series still remembered for its sustained, soap-operatic reworking of Steve Rogers's identity crisis following his resignation as Captain America and the government's installation of John Walker in the role. This issue falls within that transitional storyline, offering continuity-driven plotting and art typical of the period's Marvel house style, with Tom Morgan among the pencillers who worked the title through these years. It is a representative chapter of a well-regarded creative run rather than a stand-alone landmark issue.

Market activity reflects that status: certified sales are thin and concentrated at the high end of the grading spectrum, with only a handful of transactions recorded across 9.4, 9.6, and 9.8. The absence of recorded sales below 9.2 indicates that collector interest in raw or lower-grade copies is minimal, consistent with a late-Copper-Age direct-market issue that was printed in significant quantity and never carried first-appearance or major creative-milestone status. Demand is driven almost entirely by Captain America and Gruenwald-run completists rather than by speculative or crossover interest.

This issue suits collectors assembling a complete run of Gruenwald's Captain America or specialists in the John Walker/"Captain" storyline arc. Lower-grade raw copies trade as inexpensive fill-ins with negligible premium, while the gap between mid-grade raw material and pristine certified copies is unusually wide relative to the modest overall demand, reflecting a small population of top-graded submissions rather than broad market heat. High-grade slabs will appeal mainly to registry-driven Captain America specialists rather than general Copper Age investors.
