I look around and note the world as it is becoming. We go to a grocery store, gas station, auto parts place, auto rental place and almost anywhere and everyone is using a piece of plastic. My son hasn't had a coin or cash on him for years. We have toll roads here. They are pushing everyone to get a thing you hang in your window so you don't have to stop to pay tolls, it is automatically done. On many intersections there are cameras that photo an auto traffic violation, send you a notice by mail, you pay it with a credit card. Friends used to save their change for me to look through but now when I ask them, they tell me what change? We use plastic.
The question was what do I think will be the future of coins.
I really, honestly think that in the very near future some kid will be saying "Hey Gramps, what was that stuff you people used to use in the old days called cash?"
