SHOWCASE #24

This Silver Age key (third Green Lantern try-out issue) shows notable handling wear: a vertical crease running through the left third of the cover, soft/blunted corners, and edge wear along the right and bottom borders with some minor chipping. There is visible surface wear and slight color rubbing on the green logo panel, and the book is currently housed in a protective sleeve which shows some scuffing but appears separate from the comic. Interior and back cover were not assessed from this photo. Overall the front cover presents as a well-read mid-grade copy.

Showcase #24 (February 1960) is the third and final DC try-out issue starring the Silver Age Green Lantern, Hal Jordan, following his debut in Showcase #22 and second appearance in Showcase #23. Written by John Broome with art by Gil Kane and Joe Giella under editor Julius Schwartz, the issue helped confirm reader demand strongly enough that DC greenlit an ongoing Green Lantern series later that year, making it a foundational chapter in the character's transition from try-out feature to headline hero. The book also carries forward the Hal Jordan/Carol Ferris dynamic established in the earlier Showcase issues, a relationship that would remain central to the Silver Age GL mythos for years.

Market data shows a steep, high-slope value curve typical of scarce Silver Age try-out issues: raw mid-grade copies trade modestly in the low hundreds of dollars, while certified copies climb sharply above grade 8.5, and the highest recorded census grade (9.4) has no confirmed recent sale at all. Demand is anchored less in first-appearance status — that distinction belongs to Showcase #22 — and more in the issue's role completing the celebrated three-issue Green Lantern try-out arc, a narrative collectors and price guides consistently reference as a unit. Certified population remains thin at the top of the grading scale, which sustains a large premium gap between high-grade raw material and gem-quality slabs.

The book draws two overlapping buyer groups: Silver Age Green Lantern specialists completing the Showcase #22–24 run, and broader DC key-issue collectors building out foundational 1959–1960 material. Lower and mid-grade raw copies move steadily as affordable entry points into early Hal Jordan history, while top-census slabs are effectively unique events whenever they surface, trading opportunistically rather than on a liquid schedule. Long-term appreciation tracks closely with sustained interest in Green Lantern as a franchise and with the enduring collector premium on complete Showcase try-out sets.
