Apparently the story goes that this 20-25 year old bottle was found in 2016(?), which went viral online, and Nintendo wound up sending the guy an unopened SNES anyway. (Plus a bunch of other stuff)
In the summer of 1980 RC Cola was giving cash prizes from the bottle caps of glass bottles. None of it was serious money. I remember five, ten, and twenty five cent winners with maybe a dollar thrown in there every once in a while.
It was pretty exciting for me to find a quarter under my bottle cap. That would buy a candy bar at the time, so sugar rush bonus!
