MARVEL TEAM-UP #138

Cover shows strong gloss and sharp corners with only minor handling visible; no obvious spine stress lines or color breaks are apparent in this photo. There is a faint scratch or scuff visible in the upper black title area, and the book is protected in a plastic sleeve which limits full edge inspection. No creases, tears, or staining are visible on the front cover. Interior pages and back cover were not assessed.

Marvel Team-Up paired Spider-Man with a different guest star nearly every month, and by early 1984 the title was in its closing stretch, wrapping up in early 1985 after 150 issues. Issue #138 belongs to the run's final creative stewardship under writer Jim Owsley (later known as Christopher Priest), who scripted the majority of the series' last issues as it wound toward cancellation. The book carries no first appearance, origin, or landmark creative statement; it is a working installment of a long-running anthology-style Spider-Man vehicle rather than a series highpoint.

The certified population is substantial relative to demand, with 72 Universal copies recorded and modest sales activity even at the top of the census. Fair market value at 9.8 sits well below what recognized key issues of the same era command, and the drop-off to 9.6 is sharp despite both grades having only a handful of recorded transactions. This pattern reflects a book collected primarily as part of a complete Marvel Team-Up or Spider-Man guest-appearance run rather than one pursued on its own merits.

Buyers are typically series completists and Spider-Man supporting-cast collectors filling gaps in long boxes or CGC run sets, not investors chasing appreciation. Raw copies in low and mid grade trade near cover-price-adjusted commodity levels, while slabbed 9.8 copies carry a modest premium reflecting the difficulty of finding pristine copies of a title that saw heavy newsstand handling, without approaching key-issue territory.
