Following the course, you will have the opportunity to test your knowledge with a final exam.

U.S. currency circulates broadly around the world. U.S. banknotes, or Federal Reserve notes, are printed by the Department of the Treasury's Bureau of Engraving and Printing. They are then issued and distributed by the Federal Reserve.

Security Features

In this section, you will learn about the security features found in different denominations of U.S. currency. You will also learn simple steps to authenticate the notes you are handed when pressed for time. All you need to do is feel, tilt, and check.


Now that you know about the security features in U.S. currency and what steps to take to authenticate a note, it's time to test your knowledge. Using the information you've learned, look carefully at the security features in the following notes and see if you can identify which notes may not be genuine.
