Namor the Sub-Mariner first appeared in Marvel Comics #1, published by Marvel in 1939. That places it in the Gold Age.
Why this issue matters
Bill Everett's antihero appeared in the very first comic Timely ever published, the book that became Marvel. A version ran earlier in Motion Picture Funnies Weekly, but that was a promotional giveaway barely anyone has, so Marvel Comics #1 is the appearance collectors chase.
Marvel Comics #1 is also the first appearance of Human Torch (original android), which is part of why the book carries the weight it does.
