The United States says it will debut a new design to the hundred-dollar bill next month.

In a statement Friday, the Treasury Department said it makes decisions about currency redesigns by evaluating "ongoing counterfeit threats."

The department said the new look will help protect against fraud.

Treasury Secretary Timothy Geithner and Federal Reserve Chairman Ben Bernanke will unveil the new look on April 21 in a special ceremony.

Details of how the bill will be different from the current version have not yet been released.  But the treasury department says it will launch a global public awareness campaign to make sure everyone is aware of the new security measures before the bill starts circulating.

The hundred-dollar note is the highest U.S. dollar denomination in circulation.  It is used by people around the world.
