New $100 Bills Debut New Look and Design

The new $100 bill, which is the second most common bill in circulation behind the $1 bill, includes an array of high-tech features designed to thwart counterfeiters, reports E! Online.

The bills took more than a decade to develop and the introduction was plagued by production problems that set back the rollout by two and a half years.

"We have 3.5 billion of these notes which we think will be more than ample to meet domestic and international demands," said Sonja Danburg, program manager for U.S. currency education at the Fed, according to CBS News.

The bill redesign, the first for the $100 bill since March 1996, will still have Benjamin Franklin on the front and Philadelphia's Independence Hall on the back. It will also have a number of new features that will definitely turn heads.

There is a disappearing Liberty Bell in an ink well and a bright blue three-dimensional security ribbon with images that move in the opposite direction from the way the bill is tilted.

"The 3-D security ribbon is magic. It is made up of hundreds of thousands of micro-lenses in each note," said Larry Felix, the director of the Bureau of Engraving and Printing. "This is the most complex note the United States has ever produced."

The $100 bill is the last bill to get a makeover in a process that began in 2003 with the $20 bill. The government redesigned the greenbacks with subtle colors and other security features to make it harder for counterfeiters.
