WASHINGTON - Benjamin Franklin's face and the No. 100 are still there, but other than that, the country's new $100 bills have a whole new look.

The Federal Reserve made changes to the bill for the fourth time in history to make it harder to counterfeit, and easier to tell if it’s genuine.

Differences on the high-security bill include a 3-D blue ribbon that appears to change when you move it and a bell in the ink well.

The redesigned bills have begun circulating nationwide after officials spent more than 10 years coming up with the changes.
