Whenever I see the question about an undervalued comic book, it’s easy to come up with “nuance” books like a character’s appearing in an in house ad prior to the actual first appearance of that character in a comic book story. A nuance book tends to be the focus for the advanced collector of a specified area in comics. That focus takes the collector deeper into the area and in this case, the Golden Age (which ended with the defeat of the last of the Axis Powers in 1945). What needs to be further pointed out is that the value of a nuanced book that has the character’s in house ad appearance is really being compared to the issue with that character’s defined first appearance. Superman is an example because what’s really said about his first in house ad appearance in terms of value and it being undervalued is when it’s primarily compared to the value of Action Comics 1. The same can be said about Timely’s “lesser tiered” books like Young Allies and how it’s really compared to the Marvel Mystery Comics and Captain America titles. DC golden age collectors and those focused on Fawcetts, Fox, Nedor, and etc. are not nuanced Timely collectors comparing values between first and second tier Timely books. The other significant point here is what the impact a book had on the industry and those that followed it. None of the books mentioned come anywhere near the impact Crime Does Not Pay 22 had on the entire history of comic books and is one major reason why it’s the most undervalued GA key.
