DETECTIVE COMICS #310

This 1962 pre-direct-market issue shows notable wear: a long vertical crease running through the DC logo box and down through the character artwork at center, multiple spine stress lines and small ticks along the left edge, a corner crease at the top left, and soiling/discoloration at the lower right corner. The cover is in a protective sleeve which shows some reflection but does not obscure the visible edge and corner wear. Interior and back cover were not assessed, so overall grade may vary once those are inspected.

Detective Comics #310, cover-dated December 1962, arrives from the transitional period of Batman's Silver Age just before the 1964 "New Look" overhaul reshaped the character's direction. The issue is a standard Bill Finger-scripted Batman and Robin adventure rendered by Sheldon Moldoff in the house style of the period, typical of the science-fiction-inflected plots and imaginative death-trap scenarios that defined Batman's early-1960s output under editor Jack Schiff. It carries no first appearance, death, or origin significance and is not among the widely cited classic covers of the run, placing it squarely as a representative mid-run entry rather than a marquee issue.

The certified market reflects that status: FMVs climb gradually from the low-grade tiers through the mid-grades, with $100 holding fairly flat across 6.0 to 7.5 before stepping up through 8.0-9.0 and reaching $290 at 9.2, the highest FMV populated on the current curve. Census data shows over a hundred Universal copies graded, concentrated in the 5.0-9.2 range, with only a handful of submissions above 9.4 and just two copies at 9.8 against a single recorded sale. That top-end scarcity, paired with steady but unspectacular demand through the bulk of the grade spectrum, is consistent with a well-collected but non-key Silver Age Batman issue.

This book trades primarily on completism: buyers are Batman Silver Age run collectors filling out 1962-1963 issues rather than key-hunters, so raw copies in low and mid grades move steadily but without urgency, while high-grade certified examples command outsized premiums simply because so few exist above 9.4. A 9.8 would be a virtually unique census event for this title, and pricing at that tier should be treated as thin and volatile rather than firmly established until additional sales populate the top of the curve.
