How To Detect Counterfeit Money

The public has a role in maintaining the integrity of U.S. currency. You can help guard against the threat from counterfeiters by becoming more familiar with United States currency.

Look at the money you receive. Compare a suspect note with a genuine note of the same denomination and series, paying attention to the quality of printing and paper characteristics. Look for differences, not similarities.

Portrait

The genuine portrait appears lifelike and stands out distinctly from the background. The counterfeit portrait is usually lifeless and flat. Details merge into the background which is often too dark or mottled.

Federal Reserve and Treasury Seals

On a genuine bill, the saw-tooth points of the Federal Reserve and Treasury seals are clear, distinct, and sharp. The counterfeit seals may have uneven, blunt, or broken saw-tooth points.

Border

The fine lines in the border of a genuine bill are clear and unbroken. On the counterfeit, the lines in the outer margin and scrollwork may be blurred and indistinct.

Serial Numbers

Genuine serial numbers have a distinctive style and are evenly spaced. The serial numbers are printed in the same ink color as the Treasury Seal. On a counterfeit, the serial numbers may differ in color or shade of ink from the Treasury seal. The numbers may not be uniformly spaced or aligned.

Paper

Genuine currency paper has tiny red and blue fibers embedded throughout. Often counterfeiters try to simulate these fibers by printing tiny red and blue lines on their paper. Close inspection reveals, however, that on the counterfeit note the lines are printed on the surface, not embedded in the paper. It is illegal to reproduce the distinctive paper used in the manufacturing of United States currency.
