Counterfeit pens don't always work! We used one at my workplace and one time it didn't show that the bill was counterfeit. Here's a surefire way to tell if a bill is counterfeit or not without the person even knowing that you are checking it. Just run your fingernail over the section of the bill that is the President's suit or clothes. If you feel ridges, it's a real bill. If it feels smooth, it's counterfeit. A policeman showed me this trick and it works with old and new bills. We found more counterfeit bills this way than we ever did with the pens!
Any office supply store can order them for you with overnight or a few days notice, even if they don't have them in stock. Just ask a friendly clerk or small business owner! The good ones will be happy to help. :)
Definitely at Staples; Dri Mark Counterfeit Money Detector Pen, $4.29 for one, or package of 3 for $9.99.
