Up till recyclable bottles we used to pay a deposit on our soft drink bottles... Then wed take em back to the store and get our deposit back... Those bottles went back through the loop again several times... you could tell because there would be acutal wear on the glass...
I remember cashing in on bottles to get candy.... LOL.

Some, like the Coke bottles, would also have the city of origin stamped into the bottom of the bottle. When I was a kid, we had a game we'd play; the person whose drink bottle came from the furthest away was the "winner."
