2009 U.S Mint Set
The Mint and Proof sets issued in 2009 were unique in several ways:
• First, they were the biggest sets EVER issued by the Mint. The Proof Set had 18 coins, the Mint Set 36 pieces.
• Second, it was the only time more than 1 design of ‘Penny’ was ever included.
• Third…The pennies were made of ‘French Bronze’ like the original 1909 coins. They weren’t the Copper Clad Zinc of ‘circulating’ coins.
