My father has a vintage coca-cola machine that we are trying to identify. It is cooler style with a silver colored lid. It holds bottles not cans and they were sold for a dime a piece. Sorry I don’t photos. If anyone knows the style name or where I can find more information about the machine I would appreciate it.
Here are several that match your description:

Coke machines were manufactured by a variety of companies, so it would help if you could located the metal plate on the back that has the make and model number. Once we know the manufacturer and the model number, it is easier to determine how old it is and how much it is worth.
