Now, I'm not totally against coins - just coins that don't make sense. So while we are at it, let's get rid of the dollar bill and start using the dollar coin we have. Again, it makes perfect sense - coins last a lot longer than bills and we'll save money doing so. In fact, we are almost to the point where a five dollar coin makes sense. It is right in line with the 500 yen coin they have in Japan and those get spent. Heck, you could buy a Starbucks coffee with a single coin.
