Top 10 Green Lantern Key Issues to Own

Showcase #22 is one of the most important issues in all of DC Silver Age history. This is where Hal Jordan, an Air Force test pilot, receives the power ring from the dying Green Lantern Abin Sur and becomes Earth's new guardian for the Green Lantern Corps. This issue, written by John Broome and drawn by Gil Kane, is considered alongside Showcase #4 (Flash) as the true birth certificate of DC's Silver Age. The concept of an intergalactic police corps powered by willpower is one of the richest ideas in superhero science fiction. In CGC 9.0, it can reach $50,000 — a major investment for an absolutely foundational key issue.

Green Lantern #1 (1960) launches the first solo series dedicated to Hal Jordan following his successful appearances in Showcase. This issue confirms the character's popularity and marks the beginning of a franchise that would span over six decades. John Broome and Gil Kane lay the foundations of the Green Lantern universe: Sector 2814, the planet Oa, the Guardians of the Universe, and how the power rings work. It's a top-tier Silver Age key issue, slightly less spectacular in value than Showcase #22 but equally important to the character's history. In CGC 9.0, it's estimated around $15,000.

Green Lantern #59 introduces Guy Gardner, one of the most popular and controversial Green Lanterns in the DC universe. Abrasive, brash, and aggressive in his methods, Guy Gardner is the antithesis of conventional heroism — which makes him one of the most compelling and beloved characters among fans. Created as a backup candidate who could have been chosen instead of Hal Jordan, Guy Gardner eventually wears the ring himself and becomes a central franchise figure. His various stints as Green Lantern, Warrior, and Justice League member make this late Silver Age issue a solid key.

Green Lantern #76 marks one of the most important revolutions in American comics history. With Denny O'Neil on script and Neal Adams on art, the series takes a radical turn: Hal Jordan is confronted by an elderly Black man who accuses him of fighting for aliens while ignoring the poverty at his own doorstep. This begins the landmark Green Lantern / Green Arrow run, where the two heroes travel across America confronting the great social issues of the 1970s: racism, drugs, poverty, corruption. A courageous and unprecedented comic that redefined what the medium could express. In CGC 9.6, estimated around $10,000.

Green Lantern #85–86 publish the "Snowbirds Don't Fly" arc, one of the most courageous and controversial stories in American comics history. The arc reveals that Speedy / Roy Harper, Green Arrow's sidekick, has become a heroin addict — a subject flatly forbidden by the Comics Code Authority. DC Comics published the issues without the CCA seal of approval, a revolutionary decision that contributed directly to the progressive dismantling of the Comics Code censorship. These two issues are therefore historically unique: they represent the moment American comics refused self-censorship to tackle real social issues. Major key issues for any Bronze Age collector.

Green Lantern #87 introduces John Stewart, DC Comics' first major African-American superhero and one of the franchise's most popular Lanterns. Created by Denny O'Neil within the socially conscious GL/GA run, John Stewart is a Detroit architect who receives Hal Jordan's ring and distinguishes himself by refusing to wear a mask and by his sharp social awareness. Popularized by the animated series Justice League (2001–2006), John Stewart became the most widely recognized Green Lantern to the general public. With James Gunn's DCU plans, this issue is under close watch by collectors. In CGC 9.8, it can reach $15,000.

Tales of the Green Lantern Corps #1 is the first issue of the miniseries that expands the Corps universe beyond Hal Jordan and introduces several important characters, including Kilowog — the massive alien drill sergeant who trains new Corps recruits. Kilowog has become one of the franchise's most beloved characters, known for his catchphrase "poozers" and gruff humor. His popularity across comics, video games, and animated adaptations makes this first appearance a sought-after key issue for Green Lantern Corps fans. The 3-issue miniseries is also one of the first to systematically explore the Corps cosmology.

Green Lantern: Rebirth #1 is the start of the 6-issue miniseries by Geoff Johns and Ethan Van Sciver marking the triumphant return of Hal Jordan after years of absence and a controversial stint as the super-villain Parallax. Johns retroactively rewrites that dark chapter, explaining Hal's possession by the fear entity Parallax and restoring his reputation as a great DC hero. This miniseries literally relaunched the Green Lantern franchise and paved the way for one of the most ambitious runs in modern DC comics history. In CGC 9.8, accessible around $200 — an excellent value for its historical importance.

Green Lantern #1 (2005) launches Geoff Johns' new ongoing series after the success of Rebirth. This run would extend to issue #67 (2011) and cover the mega-events Sinestro Corps War, The Blackest Night, and Brightest Day — among the most ambitious Green Lantern arcs ever published. Johns develops the Corps mythology with unprecedented depth, introducing the various colored Corps (Yellow/Sinestro, Red, Orange, Blue, Indigo, Star Sapphire) and building a complete cosmology around emotional light. A launching pad for one of the most influential runs of the 21st century.

Green Lantern: Sinestro Corps War #1 (also numbered as Green Lantern Vol. 4 #21 depending on format) marks the beginning of one of the most popular DC mega-events of the 2000s. Sinestro, the former Green Lantern turned the Corps' greatest enemy, assembles an army of fear-powered yellow ring-bearers and launches total war against the Green Lanterns. This arc spans multiple titles, involves dozens of characters, and results in fundamental changes to the Corps' philosophy. The Sinestro Corps War event remains one of the highest-rated arcs among Green Lantern fans and an ideal entry point for the franchise.
