I was thinking recently as to what would fall in the category of the most affordable key book. A true key book: first appearances, early appearances, origin stories, iconic cover art, classic stories etc. Personally I'm a bit unsure ~
The most affordable Gold key:
The most affordable Silver key:
The most affordable Bronze key:
Strange Tales #180
The most affordable Modern key:
Spawn #1
Not sure about DC Comics which I'm rather curious about (whether it be a Showcase issue), though I'm stumped on what to put for Golden and Silver age ~
