Federal Reserve working on redesign of $100 bill to be circulated in October

Of all the American $100 bills in existence, 65 percent of them are held outside the U.S. That's part of the reason why the Federal Reserve is changing it – for the fourth time.

The Federal Reserve is trying to make it easier to be sure a Ben Franklin is genuine and harder to counterfeit.

The new $100 bill has a blue ribbon 3D strip that appears to change when you move it, adding a new "dimension" of security. 

New Benjamins, which have been in the works for 10 years, will start circulating this October.
