Is your money real or really fake?Quickly, simply, and easily, test the authenticity of US paper currency. Whether you operate a retail business handling hundreds or thousands of dollars in cash transactions every day, occasionally sell unwanted household items for cash, or simply don’t want to be stuck with a counterfeit $50 or $100 bill.
Testing the authenticity of currency is as easy as swiping the highlighter tip of this pen across a note of any value. If authentic, a yellow streak will show on the bill. If counterfeit, the yellow streak will quickly change to black. (See the picture). It’s that easy!
