On October 8, the Federal Reserve will introduce a new look for the $100 bill.
It includes advanced features including a blue 3-D security ribbon making it easier for the public to identify while being more difficult for counterfeiters to duplicate. There are bells and the numbers "100" printed on the ribbon which shift position as the note is moved.
An inkwell printed to the right of Benjamin Franklin's portrait changes color from copper to green as you move the currency, making a bell inside the inkwell appear and disappear.
And speaking of Franklin, the new $100 bill has a faint image of the founding father on the right side of the note which can be viewed by shining a light through the currency.
And if you look very closely, you can see the words THE UNITED STATES OF AMERICA micro-printed on Franklin's collar.
In case you were wondering, it costs 8 to 10 cents for the Bureau of Engraving and Printing to produce each note.
