SUPERBOY #138

Cover shows moderate wear consistent with a mid-grade Silver Age book: visible vertical creasing and waviness across the cover surface, a small crease near the top right corner box, and light corner softness at top corners. Spine area is partially obscured by the protective sleeve but appears to have some stress lines. Colors remain bright with no major fading or staining visible. Interior and back cover were not assessed.

Superboy #138 appeared on newsstands in June 1967, part of DC's long-running Superboy title chronicling the Boy of Steel's adventures in Smallville during the character's Silver Age heyday. The issue reflects the house style of the period, with Superboy stories typically built around science-fiction plots, small-town Americana, and recurring supporting cast drawn from the broader Superman mythos. It is not associated with a first appearance, origin, or other landmark event that collectors track as a key issue.

Market data for this issue is thin, consistent with a modestly collected mid-1960s DC title outside the handful of Superboy issues prized for Legion of Super-Heroes or Supergirl connections. Certified population is small across the grading spectrum, and confirmed sales cluster in the upper grades, with values climbing steadily from the low hundreds at 8.5 to the $150-180 range at 9.4 and 9.6. Demand is driven almost entirely by condition-sensitive Silver Age completists building full Superboy runs rather than by any character-specific or historical premium.

This book trades as a value-oriented Silver Age title: raw copies in low and mid grades command modest prices reflecting general Silver Age paper and nostalgia demand rather than any key-issue premium, while high-grade certified copies see a sharper price curve typical of low-census books where a handful of pedigree or fresh-to-market copies set the pace. Buyers are principally Superboy and Superman-family run collectors, with speculative interest limited given the absence of any first appearance or landmark creative credit.
