The 2010-P Lincoln cents are the first cents to depict the new Shield Cent reverse design. The Satin Finish Shield Cents were only sold to the public inside 2010 Mint Sets. In 2010, they were sold in a 28 Piece Uncirculated Coin Set.
Satin Finish: A Satin Finish coin is a coin which is not released into circulation by the United States Mint. Instead, the coins are sold in Mint Sets only. All Satin Finish coins are struck on special sandblasted planchets, also known as burnished planchets. The coins are then struck under higher pressure than circulation strike coins. Satin Finish coins are also handled with lots of care throughout the entire production process and finally inserted in to United States Mint Sets.
