Canadians will soon be lining their wallets with a different kind of plastic—revamped dollar bills designed to be virtually impossible to forge. In November, the Bank of Canada will begin circulating $100 bills made of a special polymer, which will render them slicker, smoother, and distinctly different in feel from the cotton-paper blend we’re familiar with. $50 notes will enter circulation next March and the $20, $10, and $5 bills will arrive by the end of 2013.
