New 100 Dollar Bill in October

The new $100 bill: Same old face, with some high-tech tweaks meant to thwart counterfeiters.

The United States will put into circulation a newly designed $100 bill in October 8th that aims to thwart counterfeiters with advanced security features, the Federal Reserve said on Wednesday.

The new greenbacks still bear the portrait of Benjamin Franklin, an 18th century luminary who helped found the new American republic.

The changes in design are mostly in anti-counterfeiting features such as a blue three-dimensional security ribbon and alternating images of bells and the number 100 that move and change as the viewing angle is tilted.

The Fed spells out all the cool features on its website. The $100 bill, the most widely-counterfeited U.S. note, was last redesigned in 1996. The Fed says you will not need to trade in your old $100 notes for the new ones.
