The most valuable Thor keys
Journey into Mystery #83 (1962) leads by a wide margin — the first appearance of Thor. Journey into Mystery #85 (1962), the first Loki, and #84 (1962), Thor’s second appearance, follow at the top.
The run’s villain and supporting-cast debuts fill out the list: #102 (1964) introduces Hela and Sif, and #112 (1965) features the classic Thor-versus-Hulk battle.
Later keys include The Mighty Thor #165 (1969), the first full appearance of Him (later Adam Warlock), alongside a run of scarce early-60s issues.
What makes a Thor comic valuable
Thor value is driven by first appearances and age. His early Journey into Mystery issues introduced Loki, Hela, and much of Asgard, and they’re scarce in high grade, so they anchor the list. Thor’s prominence in the Avengers films keeps demand strong.
Condition is decisive. Raw Near Mint (9.4) is the benchmark shown here; professionally graded (CGC) copies of the top keys command large premiums, and for Journey into Mystery #83 the gap between grades can be substantial.
