The $5 bill has a new look! Issued just yesterday by the US Treasury, it’s sporting a new design and security features to prevent fraud and counterfeit bills. According to Wikipedia (my info bible), here’s how to spot the new models:
Watermarks: There are now two watermarks on the redesigned $5 bill. A large number "5" watermark is located in a blank space to the right of the portrait replacing the previous watermark portrait of President Lincoln found on the older design $5 bills. A second watermark—a new column of three smaller "5"s—has been added to the new $5 bill design and is positioned to the left of the portrait.
Security Thread: The embedded security thread runs vertically and is now located to the right of the portrait on the redesigned $5 bill. The letters "USA" followed by the number "5" in an alternating pattern are visible along the thread from both sides of the bill. The thread glows blue (the previous bills glowed white) when held under ultraviolet light.
