The effort will promote the redesign of U.S. money in a campaign aimed at replacing all U.S. bills of $20 and higher starting as soon as fall of 2003.
The redesign is aimed to improve anti-counterfeiting efforts.
The Treasury Department is planning to launch the bills, dubbed "NexGen," with a $20 note, followed by $50 and $100 bills in 2004 or later.
The redesigned bills will continue to use portraits and historical images, but have subtler colors the Treasury Department hopes -- together with already introduced watermarks and security threads -- will make counterfeiting more difficult.
The steps come as improvements in copying force the Treasury to continually redesign money to stay a step ahead of counterfeiters.
According to the U.S. Secret Service, $47.5 million in counterfeit money entered into circulation in fiscal year 2001. Of this amount, 39% was computer generated, compared with only 0.5% in 1995.
