If you're asking so you can buy these issues, I have to warn you, the only first appearance that really matters is the original first appearance. Collectors don't generally pay more for the silver age, modern age, new 52, etc first appearance. Only the first first appearance. In fact, most comics that are newer than maybe 1970 aren't really worth that much anyway. I'm not trying to stop you from buying or collecting but you really shouldn't get your hopes up about cashing in.
