Quarters are a type of coin used in the United States, worth 25 cents. They are made of a mix of copper and nickel and are easily recognizable by their size and design. Each quarter features a unique image on the back, often representing a state or a significant national symbol, like the American bald eagle or George Washington. Quarters are commonly used in everyday transactions, such as buying snacks or paying for parking. They are also popular for saving and collecting. Many people enjoy collecting different state quarters, which were released as part of the 50 State Quarters Program that started in 1999.
