A five-dollar bill is a denomination of United States currency worth five dollars. It is commonly used in everyday transactions and is easily recognizable due to its distinct green color and the portrait of Abraham Lincoln, the 16th President of the United States, featured on the front. The back of the five-dollar bill displays the Lincoln Memorial, a famous monument in Washington, D.C. Five-dollar bills are made of a blend of cotton and linen, giving them a unique texture. They are part of the U.S. paper currency system, which includes various denominations for different values.
