Everyone that metal detects finds zinc pennies also called zincolns.And once in the ground they get eroded fast. A good way to clean these is by getting a rock tumbler. Hobby lobby has one for 30$ that works fine. Then get some gravel and dish soap, put the zinc pennies in with the gravel and dish soap and add some water, then wait 1 day and go back and wash the pennies off, You will be surprised at how clean they will be. www.bigboyshobbies.com
