You have a budget of $5k, what key issues would you buy???
Personally, I would buy a copy of Flash #110 (the first appearance of Wally West), then I would buy a copy of Brave and the Bold #s 54, and 57 (the first appearances of the Teen Titans and Metamorpho respectively). Lastly, with the money left over I would buy a copy of Plastic Man #1 (from 1943) (if I can find one within budget) and Showcase #22, the first Hal Jordan and Green lantern #1 (the 1960 series)
(All of these books would be low to mid-grade in order to save money and be able to afford them all haha)
I already have an extensive silver age collection, one of the perks of being a really old dude whose mom didn’t throw out my comics when I left home. Actually I’m thinking of selling off my Golden Age collection, but I’m not sure how to go about it.
