EVERY SINGLE coin operated machine in the USA would have to be altered.
Laundry machines......soda dispensing machines.....cigarette machines...the list goes on & on.
What? They’ll stop taking quarters?
All kidding aside coin machines are altered all the time.
When pop and snakes went over $1 machines were altered to take dollar bills - and 5’s.
The companies that make machines will keep making machines to take your money.
I ain’t seen a cigarette machine in years. A machine can’t card ya’.
