Collectible coins, particularly those from the United States, include a variety of types that attract numismatists. The 1 One Cent Penny, commonly referred to as the Lincoln Cent, was introduced in 1909 to commemorate the 100th anniversary of Abraham Lincoln's birth. This coin has undergone several design changes, including the Bicentennial reverse in 2009, which featured themes celebrating the 200th anniversary of Lincoln's birth. Additionally, the Shield reverse, introduced in 2010, represents a new modern design, highlighting the heritage of the U.S. currency. These variations can significantly enhance their collectible value depending on rarity, condition, and historical significance.
