Pennies are made up of many things, some of which react with other things that make them have special properties. The properties that make pennies dirty are “...2.5% copper and 97.5% zinc”(Katherine’s Chemistry Blog). The copper in penny's makes them rust or oxidize.This happens when the copper in the pennies reacts with the oxygen atoms in the atmosphere which cause rust, therefor making them apear dirty,and vinegar
