I need some information on when these came out. Cans have a Mello-Yello Tshirt and .35 cents. They were placed in vending machines. I have 6 of these un-opened, and one Coca Cola Win in a Can. Any information would be beneficial.

Does anyone remember the year that Coca Cola ran this promotion. Im thinking it was early 1980's. Any help on value would be appreciated.
