The cent is plated with a thin plating of zinc by soaking it in a mixture of sodium hydroxide and zinc dust (very dangerous and stinky too). After the zinc plating, you can shine it up and have a "Silver Penny" or heat it to amalgamate the zinc with the surface copper layer and get brass for the "Gold Penny". Post 1982 cents will often melt in a bunsen burner flame, but do pretty well if placed on a hot plate.[/QUOTE]
