Paragraph below is from the U.S. Bureau of Engraving and Printing Web page on the introduction of the new $20 note in 2003. Sounds to me as if the U.S. government is capable of preparing a coordinated, national transition program that works!
********************************************************************* "A comprehensive public education program, which was launched with the introduction of the new $20 note, continues through the introduction of other denominations. These efforts focus on communicating key security and design features of the new designs so that the public will recognize the new currency and check it to ensure genuine. This program boosted public awareness of the new $20 note's features from 73 to 85 percent, and representatives of major banks credit public education with a smooth introduction of the new $20 note."
