What about needing to give change like 0.97? They've been saying things about maybe getting rid of pennies down here in the US for years, but I don't think they've figured out how you would do so. This also raises the question, why not use a cheaper metal? Are there no practical, cheaper options? What about plastic pennies? Would they be to easy to counterfeit? Though why you would counterfeit f-ing pennies is anyone's guess.
