Pennies are made up of different percentages of copper, zinc, tin, and bronze. The first pennies were made from just copper. Now they are made mostly out of tin.
The Design Phase The U.S. Mint uses the same process to create all its coins, starting with design. To create a penny from scratch, an engraver draws the coin's likeness on paper.
Prior to 2001 pennies were made from copper, or a copper-nickel alloy; since 2001 they have been made of copper plated steel.
The interior of a penny is made of bronze.
