I collect beer cans too. I have over 1000 and a few cone tops. Coins since I was a kid. Recently started an old bicycle collection that consists of what I find at the scrap yard.
Arrowheads, but only the ones I find in my fields and I don't sell them.
Guns, especially odd actions and antiques. Old ammo and boxes.
Old signs and car tags to decorate my shop.
