I like the idea of a dollar coin. When I was in Europe I saw the sensibility of such coins.
I agree the closeness of the current dollar to the size of a quarter is stupid.
So here is a compromise that I think is ideal.
Keep the dollar coin the same size and...put a hole in the center.
Mo' savings!

Great! I could drill a hole in a Levi's jean button and pass it off as dollar!
