CHAMBER OF DARKNESS #6

Cover shows good gloss and bright inks with no major creases visible; corners appear reasonably sharp with only slight blunting at the bottom right. There is minor edge wear along the top and right edges and a faint vertical line near the spine that may be a light stress line rather than a full crease. The book is housed in a protective sleeve which obscures fine detail and possible spine ticks. Interior pages and back cover were not assessed.

Chamber of Darkness #6 (August 1970) is one of only six issues in Marvel's short-lived Bronze Age horror-anthology line, launched as the company expanded beyond superheroes into mystery and suspense fare aimed at the era's newly loosened Comics Code restrictions. Like its sister titles, it presented multiple self-contained short stories rather than a continuing narrative, drawing on a rotating bench of Marvel's bullpen writers and artists working in a moody, EC-influenced horror idiom. The series has never carried a marquee first appearance or origin story, and its historical interest lies chiefly in its place within Marvel's brief early-1970s horror-anthology experiment rather than in any single celebrated contribution.

Market data shows a typical low-print-run anthology profile: a small but real population of high-grade certified copies commands outsized premiums, with values climbing steeply from the mid-grade range up through 9.6 and 9.8, while mid- and low-grade raw copies trade for modest, largely incidental sums. Demand is driven less by any single collectible element than by completism among Bronze Age horror-anthology collectors and by the scarcity of pristine surviving copies, since anthology titles of this vintage were read and discarded rather than preserved.

This is a book for anthology-focused Bronze Age collectors and completists assembling the Chamber of Darkness run rather than for key-issue investors. Raw copies in low and mid grade are inexpensive and readily available, changing hands mainly as filler in longer horror-anthology runs, while certified copies at the top of the grading scale are genuinely scarce and trade at a significant multiple over anything below 9.4, reflecting condition rarity rather than content-driven demand.
