DETECTIVE COMICS #401

Cover shows notable spine wear with a visible vertical crease and stress line running down the left edge, plus small chips/tears along the spine. Corners show blunting, especially the lower left. There is general surface wear and a slight fold at the bottom left corner. The book is in a protective sleeve which causes some glare; interior and back cover were not assessed.

Detective Comics #401, cover-dated July 1970, arrived one issue after Frank Robbins and Neal Adams introduced Kirk Langstrom's Man-Bat in Detective Comics #400. This follow-up, "Man-Bat Over Vegas," continues the character's early run during the Adams-defined Batman era, when the artist's moody, anatomically dynamic covers were reshaping the visual identity of the Dark Knight line. Robbins scripted the Man-Bat stories through this stretch, with Adams contributing the cover work that anchors the issue's collector appeal.

Market data shows a comic that trades steadily rather than spectacularly through the mid-grade range, with certified sales holding near $50-60 across grades 4.0 through 8.0 before the curve steepens sharply above 9.0. That inflection point, where 9.4 copies have brought roughly four times the 9.0 price, indicates that demand concentrates heavily at the top of the census rather than across the run. With no 9.8 copies yet sold despite five appearing on the certified census, the highest grades represent a thin, contested tier where pricing is driven more by scarcity of transactions than by depth of demand.

This book suits Bronze Age Batman collectors building out the Man-Bat and Neal Adams cover runs rather than buyers chasing a singular landmark key. Raw and lower-grade certified copies remain accessible and change hands as reading or run-filling copies, while high-grade submissions attract targeted competition from cover-art and character-completist collectors. Long-term interest tracks closely with Man-Bat's ongoing visibility in Batman media and reprint collections, which continues to sustain a modest but consistent demand curve across the grade spectrum.
