What the Eye is
Stan Lee and Steve Ditko introduced the Eye of Agamotto pendant in Strange Tales #110 (July 1963) as part of Doctor Strange’s costume. The named ‘Eye of Agamotto’ designation came in Strange Tales #115 (December 1963), with the truth-revealing mechanic and the cosmic-entity origin (Agamotto, one of the Vishanti) established. The MCU adapted the Eye as the Time Stone’s housing in Doctor Strange (2016).
Collector context
Strange Tales #110 trades in the high four to low five figures at CGC 9.0 and above. The Eye’s first-appearance value is folded into the Doctor Strange debut pricing.
