MARVEL TWO-IN-ONE #29

Cover shows strong gloss and vivid color with sharp corners and no visible creasing or spine stress lines; a faint diagonal reflection near the center appears to be light glare rather than a surface scratch. Edges appear clean with no chipping or fraying visible. The book is in a protective sleeve, which limits full assessment of spine and edges, and the back cover and interior were not examined. Based on visible surface quality alone this appears to be a high-grade near-mint copy.

Marvel Two-In-One #29 (July 1977) pairs Ben Grimm with Shang-Chi, Master of Kung Fu, in a crossover written by Marv Wolfman with pencils shared by Rich Buckler and Ron Wilson and inks by Frank Giacoia and Sam Grainger. The issue also features an early guest appearance by Spider-Woman, who had debuted only months earlier in Marvel Spotlight #32; this is not her first appearance but reflects Marvel's rapid effort to integrate the character into the wider line following her launch. The book is representative of the team-up format's mid-1970s appeal, blending street-level martial arts with cosmic and monster-adjacent Marvel continuity through the Thing's rotating cast of guest stars.

Market data shows a typical long-tail Bronze Age distribution: certified population is substantial (103 Universal copies across 105 total graded), sales activity is thin below 9.0, and value climbs steeply only in the top third of the grading scale, jumping from the mid-teens at 9.0-9.2 to $70 at 9.6 and $100 at 9.8. This curve indicates a book bought primarily by CGC 9.8 registry completists and Spider-Woman or Shang-Chi guest-appearance collectors rather than by demand tied to any singular key moment. Raw and low-grade copies see negligible collector interest beyond bulk-run or reading-copy buyers.

This issue trades as a filler/support book for Marvel Two-In-One and Thing runs, with most transactional heat concentrated at the CGC 9.8 tier where population remains comparatively low relative to demand from registry builders. Mid-grade raw copies move slowly and mostly through bulk lots or dollar-bin acquisition by team-up and Shang-Chi completists, while low-grade copies carry essentially reading-copy value. Long-term appreciation, if any, will likely track continued interest in Spider-Woman's early Bronze Age appearances and Shang-Chi's crossover history rather than any inherent scarcity of the issue itself.
