I'm intrigued by the U.S. Govt's actions to get people to think more 'green' with their money by lessening the use of paper money which costs the govt a lot more to make then it does to make (and recycle!) coins (which also last a lot longer).
Read the article on the govt's initiative to get us to use dollar coins here.
...Then tell me what you think. Would you carry dollar coins in your pocket instead of paper in your wallet?
