The Quarter is a coin in the United States. It is equal to 25 cents, or one-fourth of a dollar. Sometimes it is also called "two pieces of eight" or "two bits". The quarter has a silver coloring and ridges along the circumference of the coin.
On the back, or reverse, an eagle was featured until 1998; since 1999 the eagle has been replaced with designs commemorating each of the 50 states.
