If we minted them with aluminum like Japan's yen, the cost would be lower. But the zinc producers are lobbying against this. The cent is 95% zinc and 5% copper. There is more than a cent worth of copper in pre-1982 pennies, but it is now (since 2007) illegal to melt them or export them outside the U.S. Pre-1982 cents are 95% copper and 5% zinc, save them.
