DETECTIVE COMICS #267

This is the iconic 'Batman Meets Bat-Mite' cover (first appearance of Bat-Mite), but the copy shows extensive amateur ballpoint-pen scribbling across the entire cover art, which is a major, permanent defect severely impacting value. Additional issues include pressure-sensitive tape strips along the top and side edges (likely from prior storage), overall paper browning/foxing consistent with age, soft rounded corners, and minor edge wear. Interior and back cover were not assessed in this photo, but the pen markings alone place this well into the low-grade range despite the cover otherwise being complete and structurally intact.

Detective Comics #267 (May 1959) introduced Ralph Dibny, the Elongated Man, in a back-up feature written by John Broome with art by Carmine Infantino, whose loose-limbed stretching hero arrived as DC's Flash-driven superhero revival was gathering momentum. The character would go on to headline his own back-up strip for years and later join the Justice League of America, giving this issue lasting standing as a genuine first-appearance key of the early Silver Age rather than a book noted merely for its cover or Batman content, which remained the lead feature.

Demand tracks the broader Silver Age key market: certified population is substantial for a book of this vintage (293 Universal copies across 315 total graded), yet high-grade material thins sharply above 8.5, and no copy has ever certified above 9.4. Pricing data shows a pronounced curve — mid and low grades trade in a tight, liquid band under $1,000, while grades from 6.5 upward escalate quickly, and the sole 9.2 sale command well into five figures, reflecting how few well-preserved copies of this fragile, cheaply-produced ordinary-issue survive.

The book draws two overlapping buyer pools: Silver Age DC key collectors building runs around Justice League-adjacent first appearances, and Elongated Man/Flash-family specialists completing character-origin sets. Lower and mid-grade raw copies move steadily as accessible entry points into the key, while true high-grade certified examples are scarce enough that a 9.8 has never reached market — any such copy would likely set a new benchmark well above recent top sales rather than simply extend the existing curve.
