DETECTIVE COMICS #380

Cover shows good color and gloss with no major creases visible; slight softness at the top corners and minor edge wear along the right border. There appears to be a faint vertical crease/waviness in the lower right portion of the cover. The book is housed in a protective sleeve which limits full assessment of spine stress lines and corner sharpness; interior and back cover were not assessed. No visible tears, stains, or writing on the front cover.

Detective Comics #380 (October 1968) arrived during a period when the Batman titles were transitioning away from the campy tone of the mid-1960s television era back toward a harder-edged detective format, with Irv Novick handling much of the cover and interior art on the series and Frank Robbins contributing scripts. The issue features a standard Batman and Robin adventure of the period, produced during a stretch of Detective Comics that is collected primarily for its place in the larger Silver Age Batman run rather than for any single landmark event within its own pages.

The certified population for this issue is substantial, with 131 Universal copies recorded across the CGC census, reflecting steady but unspectacular collector demand typical of secondary Silver Age Batman issues from the late 1960s. Fair market values across the grade spectrum are modest and fairly flat through the upper tiers, with 9.4 and 9.6 both realizing around $170 in recent sales, and mid-grade copies (4.0 to 6.0) trading in the mid-$30s. The absence of any 9.8 on census, despite two copies graded at that tier, signals that top-end supply is essentially untested at auction, leaving room for a rarity premium whenever a pristine copy does surface.

This issue trades as a run-filler for Batman and Detective Comics completists rather than as a marquee acquisition, and pricing across grades should be expected to move incrementally rather than in sharp jumps. Entry-level and mid-grade copies remain widely available and inexpensive, making the book accessible to collectors building out the full 1960s Detective Comics run, while a certified 9.8, should one appear, would likely command a premium disproportionate to the plateaued values seen at 9.4 and 9.6 simply due to its census scarcity.
