2009 Philadelphia and Denver Mint Uncirculated Coin Set ( P & D ) . The 2009 set is considered an important and distinctive set for collectors due to: _ The original copper composition in the Lincoln pennies is 95% copper (the same as the original 1909) and the four distinctive designs specific to this issue. _ The satin finish of the coins has a smooth, matte texture resulting from a special striking process. _ Low mintage: A smaller number of coins were produced, especially the dimes/nickels, making these versions highly valuable. The set consists of 36 coins divided between two mints, Philadelphia (P) with 18 pieces and Denver (D) with 18 pieces. Includes: . 12 quarter dollar coins (Washington Quarters) with 6 designs from each mint as part of the U.S. Territories and Possessions Program (Puerto Rico / Guam / American Samoa / Virgin Islands / Northern Mariana Islands). . 8 one-cent coins (Lincoln Pennies) with 4 different "Lincoln Bicentennial" designs from each mint, commemorating the stages of Abraham Lincoln's life (Birth / Formative Years / Professional Life / Presidency). . 8 one-dollar coins (Presidential Dollars) featuring 4 presidents from each mint (William Harrison / John Tyler / James Polk / Zachary Taylor). . 2 one-dollar coins with the "Native American" design (Three Sisters Agriculture). . 2 half-dollar coins (Kennedy) P&D . 2 five-cent coins (Jefferson Nickel) P&D . 2 dime coins (Roosevelt Dime) P&D
