FWIW,
From Michigan law books/newspaper article:
"Michigan. 1950s, most beverage. United Conservation containers were made. Clubs (MUCC) distrib- from glass. Consumers uted petitions around paid a small deposit"
It was 2 Cents per bottle for refillable soda, beer, bottles only. I lived it as a child and had collected a heck of a lot of those 2 cent'ers myself and took them to the store to get my money! It said refillable in raised letters down on the side at the very bottom of the bottle! If the "refillable was not there, not accepted for a refund. I do not know if anyother states had a similar deposit setup back then but Michigan sure did!
The 10 cents deposit and refund was established by law in Michigan in 1976 to cover glass, plastic, and aluminum beverage containers. Back in the 1950's and before only glass was used for bottles and refillable bottles. That's where the name "bottles" came from! Glass!
