The Original Smart Money™
Counterfeit Money Detector Pen
US currency is printed on a special paper. The patented Counterfeit Detector Pen is a chemical test to determine authenticity. Uncap the pen and make a small mark on any US currency bill. If the mark is yellow or gold, the money passes the test. If the mark turns dark, the currency is suspect. Ideal for retailers, restaurants, stores, banks or any cash business.
