THE FLASH #171

Cover shows moderate wear consistent with a mid-grade Silver Age book: visible vertical creasing across the lower half and through the central figure, a horizontal crease near the bottom, and some surface wrinkling/waviness affecting the red costume art suggesting slight moisture exposure at some point. Corners show light rounding with no major chips, and the spine appears intact without major splits, though slight stress lines are visible. The book is in a protective sleeve, which obscures fine edge detail, and the back cover and interior pages were not assessed.

The Flash #171 (DC Comics, June 1967) is a representative mid-1960s issue from Barry Allen's flagship Silver Age title, produced during the era when John Broome scripted most Flash stories and Carmine Infantino defined the character's visual language, with Murphy Anderson providing inks on many covers of this vintage. The issue sits within a long, tightly continuous run that collectors pursue as a set rather than for any single landmark event, reflecting DC's steady science-fiction-inflected superhero formula of the period: high-speed rescues, pseudo-scientific menaces, and Infantino's signature kinetic figure work.

Market data shows a typical long-tail Silver Age curve: certified sales are thin and prices modest through the mid grades, climbing sharply only at the top of the census. Demand is driven almost entirely by Flash Silver Age completists and CGC 9.6-9.8 registry builders, since the issue carries no first appearance, death, or other headline event to draw crossover buyers from outside the title's fanbase. The gap between the small population of 9.6/9.8 copies and the much larger mid-grade population explains the outsized jump in value at the very top of the grading scale.

This is a book that trades as a filler or set-builder in low and mid grades, where price is governed by general Silver Age DC demand rather than issue-specific interest, and as a runner in high-grade registry competition at 9.6 and above. Buyers at the low end are typically completists filling gaps in a Flash run; buyers at the high end are registry-focused collectors chasing one of the handful of surviving 9.8 copies, where scarcity rather than content drives the premium.
