Looks like you still have some nice ones left! I was thinking of going for the Silver Surfer run when I'm done with Spider-man since it's only like 18 issues. AF 15 is probably something I'll never get. It's going around $5k for a 1.0 nowadays...
While we're talking comics, here's a few I have laying around from another run I have complete sans #1. Along with TMNT collecting, I love silver age Marvels...which doesn't make a whole lotta sense since I wasn't even born until the late '70s.
