A Demand Note is a type of United States paper money that was issued between August 1861 and April 1862 during the American Civil War in denominations of 5, 10, and 20 US$. Demand Notes were the first type of paper money issued by the United States in the sense that they were the first in the series of emissions which has continuously achieved wide circulation down to the present day. The U.S. government placed the Demand Notes into circulation by using them to pay expenses incurred during the Civil War including the salaries of its workers and military personnel.
