America's new $100 notes start circulating this fall

America's new $100 note, which will start circulation this fall, have a host of new security features, says the US Federal Reserve.

There is a new 3-D security ribbon that is woven into the bill, slated for circulation October 8, 2013. When the bill is tilted an image of  several 100s will move from side to side. There is also a copper-coloured inkwell that changes shade depending on what angle the note is viewed.

Other redesigned denominations will be rolling out: $50, $20, $10, and $5 notes.

Consumers and businesses will not have to trade in older $100 notes for new ones, says the Fed. Older designs of Federal Reserve notes remain legal tender, and will not be recalled, demonetized, or devalued.

The Federal Reserve says that over a decade of research and development went into the new security features. The new security features are being promoted to help better identify counterfeits. The US Government has a web site up covering the new features.

"Even with the most technologically advanced security features, it’s you — the educated consumer — who continues to be the best line of defense against counterfeiting.

"It only takes a few seconds to check the new $100 note and know it’s real. Learn how to identify and use the two advanced security features: the 3-D Security Ribbon and the Bell in the Inkwell."
