BATMAN #128

Silver Age Batman with heavy wear typical of the grade: significant spine stress with visible creasing and color break along the spine edge, corner rounding at top left and bottom corners, and general surface wear/soiling across the cover. There appears to be a small tear or crease at the upper left near the DC bullet, and the cover shows overall aging/darkening consistent with a book of this age. The comic is protected in a plastic sleeve; interior pages and back cover were not assessed.

Batman #128 (DC Comics, December 1959) introduces Bat-Mite, the mischievous imp from another dimension who idolizes Batman and repeatedly complicates his cases with unwanted "help." Credited to writer Bill Finger with art by Sheldon Moldoff under the studio's Bob Kane byline, the character was conceived as a direct analogue to Superman's Mr. Mxyzptlk, giving the Batman titles their own whimsical fifth-dimensional troublemaker. Bat-Mite would go on to recur throughout the Silver Age and later become a fixture of animated and modern comics interpretations of the Bat-family, cementing this issue's status as a recognized first appearance within the Batman canon.

Market data shows a typical Silver Age demand curve for a well-collected but non-flagship issue: mid and low grades trade in a narrow, largely flat band, while values accelerate sharply above 8.5 as eligible near-mint copies become scarce. With no 9.8 recorded across a census of over one hundred graded copies, the top of the pyramid remains unclaimed, and any copy reaching that tier would command a substantial premium over the highest verified sales. Demand is driven less by cover imagery than by the character-first-appearance premium, a dynamic increasingly common for Silver Age office issues once the featured character develops a longer cultural footprint through television and modern reprints.

The book suits collectors building character-first-appearance runs alongside core Batman keys, as well as investors targeting scarce high-grade Silver Age material with upside tied to census gaps. Lower and mid-grade copies remain accessible and trade steadily as reading or completist copies, while high-grade and unslabbed-but-pedigreed examples see disproportionate bidding activity whenever they surface, reflecting the thin population at the top of the grading scale.
