Comic Description
First appearance of Guy Gardner. In the story 'Earth's Other Green Lantern!', the Guardians show Hal Jordan that if he hadn't been chosen by Abin Sur's ring, Guy Gardner would have been the one to wear it. The issue explores an alternate reality and marks the beginning of one of the most famous Green Lantern characters.
Condition & Value
Condition Grade
Very Good (CGC 4.0)
Condition Details
Visible spine stress and color-breaking ticks throughout the left edge; significant cover scuffing and surface wear (particularly in the green/white areas); corner blunting and minor rounding; some minor soiling and yellowing of the cover paper stock consistent with age; possible small tear/crease on lower right edge.
Estimated Market Value
Raw: $250 - $350 | Graded (4.0): $400 - $550
Recent Sales
Recent 4.0 CGC copies have sold between $450 and $575. Raw copies in similar mid-lower grade typically fetch $300 due to the high desirability of Guy Gardner's debut.
Grading Recommendation
Yes, worth grading. While it is a mid-grade copy, this is a major Silver Age key (1st Guy Gardner). Professional cleaning and pressing could potentially bump this to a 4.5 or 5.0, significantly increasing liquidity and protecting the value.
Notable Features
First appearance of Guy Gardner (later a member of the Justice League and a major GL protagonist). Iconic Gil Kane cover art. Silver Age DC key issue.
Authentication Notes
The item appears to be an original 1968 publication with genuine 12-cent price marking, period-correct DC logo, and appropriate Ben-Day dot patterns visible in the printing. No immediate signs of restoration or counterfeiting are visible from the image provided.
