When a copper penny is zinc plated it will appear to change from its copper color to silver color. And by using sufficient heat, a zinc plated copper penny can be changed to a shiny gold color. This version of Silver and Gold Pennies utilizes zinc sulfate as less caustic than sodium hydroxide and works just as well.
