DETECTIVE COMICS #390

This 1969 pre-direct-market issue shows moderate wear: visible spine stress lines and a couple of small ticks along the spine, a diagonal crease running through the upper left corner near the DC bullet, and general surface wear with slight corner softness at top right. The cover retains good color and gloss without major stains or tears, but there is a bend/crease affecting the top edge and mild handling wear throughout. Book is in a protective sleeve, which may obscure some edge detail; interior and back cover were not assessed.

Detective Comics #390 arrived in August 1969, during the transitional period when Batman's adventures were being reshaped by writer Frank Robbins and regular penciler Bob Brown following the departure of the show-era campiness and ahead of Neal Adams's celebrated run on the title a few issues later. The book reflects DC's push toward a moodier, more detective-driven Batman as the company retooled the character for the 1970s. It carries no first appearance, death, or origin story, and its cover, while representative of the era's house style, is not among the classic covers cited in price guides.

Market data shows a thinly traded but consistently collected book: certified sales are modest in volume across all grades, with fair market values climbing steadily from the mid-grade band into the low $100s at 8.5, and no completed sales recorded above 9.6 despite a small population reaching that grade. This pattern is typical of a solid but non-key mid-run Silver Age Batman issue — demand is driven primarily by Batman run-completists and Bronze/Silver transition-period collectors rather than by character-first-appearance buyers, keeping raw and mid-grade values restrained.

The book trades as a run-filler for Detective Comics and Batman title collectors, with raw copies moving steadily at low prices and mid-grade copies attracting little competition. High-grade certified copies are scarce enough that a 9.8, should one surface, would command a meaningful premium over the current 9.6 population purely on condition rarity, but this remains a book bought to complete a title run rather than pursued as a standalone key.
