The new US $5 bill was unveiled for the very first time in a very unique way on 20th September 2007. For the very first time Paper Money was unveiled live online. Here is a video of the presentation from the US Bureau of Engraving and Printing.
Previously the $10,$20 and $50 notes had been redesigned and their unveiling was not an online presentation. This was an entirely digital event, which took place as a "Wii-5" preview on www.moneyfactory.gov there is also an online Question and Answer session for Reporters and Podcasts featuring important information about the new $5 bills.
The new $5 bill is smarter, safer and more secure according to The Bureau of Engraving and Printing and really anything a government can do to make its paper money more safe and secure is more than welcome. Counterfeiters are always trying to improve their game a government that does not stay a couple of steps ahead of them will find that they have more counterfeits in circulation than real genuine currency. The changes and redesign of the $5 bill will make it much more difficult for these $5 notes be changed into $100 notes as was the previous practice.
