In Canada, our coins have a picture of the Queen stamped on one side, and an animal on the reverse. Several years ago, the $1 bill was replaced with a $1 coin, with the loon (a bird) on the reverse. This coin is commonly called a 'loonie'. A new coin will be released to replace the $2 bill. The animal on the reverse of the $2 coin will be a polar bear. There are a number of proposals for a common name for the new coin. Joseph A. Torbay, Cambridge, Ontario, writes in a letter to the local newspaper (paraphrased): "Apparently, the coin shows the Queen in front, and a bear behind. Maybe we should call it the 'moonie'."
