I found this while going through my grandpa's estate. They were kept in a safe dry place for years. I know nothing about older ammo so I was hoping someone could let me know what I have?, what to do with it? or maybe what it's worth? Any help would be appreciated. Thanks 
Oh yeah...on the bottom of the cartridge there is a "CF" and a "star"...if that means anything
