How I would love to walk into a McDonalds and pay with a single coin. It has a bit of a romantic image. But businesses are not likely to accept silver coins anytime soon and the gov is unlikely to make new coins that actually keep up with inflation and have some value, so my image will have to remain just that. I can get close to it in Japan, with the ¥500 coin, but even that one is being made less and less useful from inflation.
