If you go to your local bank and the cashier gives you a $5 bill that looks a little strange don't worry , you probably have been given the new $5 bill that goes into circulation today. The new $5 bill is more colorful than the previous version and also is harder to counterfeit.

"The redesigned $5 bill's enhanced security features help ensure we stay ahead of counterfeiters and protect your hard-earned money," Michael Lambert, Assistant Director, Division of Reserve Bank Operations said in a press release. "It only takes a few seconds to check the new $5 bill to make sure it's genuine. If you know how to check its security features, you can easily be confident it's real."

Here are some of the key changes to the new $5 bill:

* The large easy-to-read number “5” in the lower right corner on the back of the bill, which helps those with visual impairments to distinguish the denomination, has been enlarged in the new $5 bill design, and is printed in high-contrast purple ink.
* The oval borders around President Lincoln’s portrait on the front, and the Lincoln Memorial vignette on the back have been removed. Both engravings have been enhanced.
* An arc of purple stars surrounds the portrait and The Great Seal on the front of the bill, and small yellow “05”s are printed on the front and back of the bill.
