Don't know about the others but the Norm Edwards are definitely worth keeping. I took a couple of mine to the lure show to see if they were worth keeping and was offered $400 for the both of them. One of them was in worse condition than yours. If you put a post on the Lure Lovers forum they will have an idea.
Heres some stuff on the others
