Pennies today are made of zinc blanks (circles of zinc are punched out of sheets of zinc, like cookies are cut out of a sheet of dough with a cookie cutter). The zinc blanks are then electroplated with copper in plating barrels (we have an article with pictures on line about barrel plating), so the core of the penny is zinc but the skin is copper.
After the copper plating, they are stamped with the familiar head of Lincoln and the date, etc. Coins such as pennies have a raised rim (the lip around the penny is thicker than the body of the penny); this is created by rolling the coin through a passage that is slightly smaller than the original size of the blank. The higher edge helps protects the design from excess wear.
