About the character
Thaal Sinestro, once the greatest Green Lantern in the Corps, became a villain convinced that fear is a more effective force than willpower. His first appearance in Green Lantern #7 is a sought-after Silver Age key.
What is a first appearance worth?
Green Lantern #7 has solid collector demand. A presentable raw copy in the UK typically attracts an offer in the low to mid three figures; high-grade or CGC-slabbed examples can push into four figures. Restored copies are worth less but still very much wanted — we buy across all grades and conditions.
Exact figures depend on grade and condition. See the full Green Lantern #7 valuation guide →
