The first American paper money was printed in 1690, when the Massachusetts Bay Colony printed Colonial Bills. 85 years later, Continental Congress Currency was issued in 1775 to finance the Revolutionary War. In an effort to finance the Civil War, the U.S. Treasury issued paper money in the form of “demand notes”, also called “greenbacks”. Throughout the years, currency with beautiful artwork was issued, such as the $20 bank note, the $2 Silver Certificate, and the $10 U.S. Note.
