The zinc within a copper penny does not oxidize because of an impossible build up of charge. The zinc atoms lose electrons to the copper atoms, creating a positive charge on the zinc atoms and a negative charge on the copper atoms. This charge difference creates an electric field that prevents further oxidation of the zinc.
