In the 1950s and maybe into the '60s, many were actually called 5 and 10 cent stores. There was an Emery 5 and 10 cent store in my home town.
And kids did call those the dime store, and sometimes the 5 and 10.
Coca Cola bottle was 5 cents. Some manufacturing facilities had long-term agreements with Coca Cola bottlers that continued into the 1970’s. You could get a cold bottle from the all-manual Coke machine for 5 cents in 1972.
