In your opinion, why has the U.S. Mint made their pennies of mostly zinc rather than copper? Copper has antibacterial properties (i.e., it can kill bacteria on contact) Does this explain why so many coins contain at least some copper? Explain your reasoning S. Many doorknobs have some copper alloy (brass, bronze, etc) Why do you think this is?
