One cent is a unit of currency that represents one-hundredth of a dollar. It is often denoted by the symbol "¢" and is commonly used in various currencies around the world, including the United States dollar and the Euro. Coins worth one cent are typically made of metal and are small in size, making them easy to carry. In the United States, the one-cent coin is known as the penny. It features the image of Abraham Lincoln on the front and the Lincoln Memorial on the back. Although its purchasing power has decreased over time, the penny remains a part of everyday transactions and is often used for making change.
