The Bureau of Engraving and Printing and the Federal Reserve unveiled a new $20 bill earlier this week. The newly designed $20, which will go into circulation in the fall, will still be mostly green, but it also will be pale blue, light peach, yellow, and copper. (See image below)This is the first time in a century that US bills will be multicolored. From 1869 to 1905 bills from $1 to $1,000 were printed in a variety of colors to thwart counterfeiters. During the Civil War, approximately one-third of all bills were counterfeit.
