Each dollar bill costs 10 cents to print. Each dollar coin costs about 10 cents to mint. Congress used to argue that a dollar bill was cheaper to print, but since cotton has gone up in price, both are nearly the same price (10 cents). A dollar bill only lasts about 2 years. Pull out the ones that you have, I bet over 75% of them are series 2009. A dollar coin on the other hand, lasts THIRTY YEARS, or more. So in a dollar coin's lifetime, 15 dollar bills will be printed. So what makes more sense, making something for 10 cents that lasts 30 years, or printing something for 10 cents that lasts 2? How do you confuse a dollar coin with a quarter? If your looking at your change, dollar coins are easily spotted by their gold color. If your digging in your pocket the dollar coin has a smooth edge, and the quarter has a rough, reeded edge. There are also people who argue that the coins will weigh them down. "I don't want to carry twenty of them in my pocket." Who carries twenty 1 dollar bills? Exactly... Canada has not used dollar bills since 1989. We need to stop being such a stick in the mud.
