Detecting counterfeit money

These days, counterfeit paper money

is usually made with color printers or

color copiers. The U.S. Treasury has

redesigned the 5, 10, 20, and 50 dollar

bills with security features that make

them harder to counterfeit. Printers

and copiers can’t reproduce those

features, so they are what you should

pay attention to. Try this with one of the

new redesigned bills, not an older one

or a one dollar bill.

Paper money test

You will need:

Magnifying glass

UV flashlight

Lamp (for watermark)

Different denominations of paper

money

Here’s how:

1. To find a counterfeit, it usually

helps to view the bill at different

angles. With a real 10-, 20-, 50-, or

100-dollar bill, the numeral in the

lower right-hand corner changes

from green to copper as you tilt it

from side to side.

2. Hold the note up to the light and

look near the right edge for a face

similar to the one printed in the

center. Also, look for the security

thread strip, which repeats the

words “USA FIVE,” “USA TEN,”

“USA TWENTY,” “USA 50,” or “USA

100” in tiny print.

Security threads glow in UV light

The security threads embedded in newer

bills each glow a different color in UV

light. Try shining the Multi-Pen light on the

security threads of different bills.
