Catch a Counterfeit:
3 Ways to Tell if a Bill Is Authentic
Color-Shifting Ink. If you hold the one of the most recent series $10, $20, $50 or $100 bills and tilt it back and forth, you can observe the numeral in the lower right hand corner as its color shifts.
Watermark. Hold the bill up to a light to view the watermark in an unprinted space to the right of the portrait. The watermark can be seen from both sides of the bill since it is not printed on the bill but is imbedded in the paper. Please note that the position, size and relative density displayed below are for illustrative purposes only and are approximate.
Security Thread With Microprinting. Hold the bill up to a light to view the security thread. You will see a thin imbedded strip running from top to bottom on the face of a banknote. In the $10 and $50 it is located to the right of the portrait, and in the $5, $20, and $100, it is located just to the left of the portrait. The $5 bill has USA FIVE written on the thread; the $10: USA TEN; the $20: USA TWENTY; the $50: USA 50; and the $100: USA 100.
