A coin wrapper, sometimes known as a bank roll or roll is a paper or plastic container for a number of coins. In the United States, empty rolls are available free at most banks in every denomination (though it is becoming increasingly difficult for half dollar and dollar to be readily made available). The rolls come flat and one side will have to be folded to allow for coins to be placed inside. When the roll is full, the top side will need to be folded. Typically, the full rolls are brought back to the banks in exchange for currency or to be deposited.
