A new penny is partially made from bright, shiny copper. But after a while, it loses its shine because the copper mixes with the oxygen in the air and makes a coating called an oxide. When you put the penny in lemon juice, the acid in the lemon chemically removes the oxide, and you're left once again with a bright copper penny.
