Thirty-five million new $1 coins have become available for distribution, beginning the end of Canada's $1 bill in a plan the government said will save millions of dollars in production costs because $1 bills wear out more rapidly than coins. The coins are gold-colored and show a loon on one side and Queen Elizabeth II on the other. The coins are being distributed through banks and trust companies throughout Canada, Royal Canadian Mint spokesman Michael Francis said. The mint has an additional 65 million coins available. The $1 bills are to be gone by the end of 1990.
