I have some old targets that my Dad bought probably in the 50's: Remington Peters (DuPont) Standard Short Range Target (50feet); NRA Official 50YD Small Bore Target printed by Wisler Western Arms, Inc; and Williams 50-yard Small Bore "Dial Scoring" Target. Is there any collectors values to these or should I just shoot them up?

Check on Ebay. Some people buy them to frame. Won't be a gold mine but will be worth more then paper to shoot at.
