2011 United States Mint Set in Original Government Packaging! 28 Coins Inside!. After six years of utilizing a special satin finish for the annual mint set, the United States Mint switched to using a brilliant finish for coins included within the 2011 Mint Set. According to the Mint, the reason for the change was to create more aesthetically pleasing coins, as the previous finish made contact marks from coin on coin contact more apparent. The new brilliant finish was produced by striking coins on special presses using greater than typical force to create an intricately detailed image. Despite higher strike quality and more lustrous surfaces, the coins are typically not differentiated as separate issues from standard circulation strikes.A total of 28 different coins were included in the set. The historically high number of coins in the set was the result of the multiple designs issued under the America the Beautiful Quarters and the Presidential Dollars Programs. Each set included the following coins: P&D Lincoln Cents. P&D Jefferson Nickels. P&D Roosevelt Dimes. P&D America the Beautiful Quarters (Gettysburg, Glacier, Olympic, Vicksburg, Chickasaw). P&D Kennedy Half Dollars. P&D Presidential Dollars (Andrew Johnson, Ulysses S. Grant, Rutherford B. Hayes, James Garfield). P&D Native American Dollars. The design for the packaging was updated to match the new brand identity and logo adopted by the United States Mint. The logo consists of a golden colored coin flipping through the air against a black background.
