OK, here's another question: we sold the old washer and dryer for $100 back in January and the guy walks up and hands me a $100 bill. Now I've heard that there is a lot of counterfeiting going on and obviously if you're going to counterfeit, you might as well make it a big bill, right?

Near as I can tell our bill was genuine (at least the bank accepted it) but it got me to wondering....

It occurred to me that buying and selling on CL would be a good way to spread counterfeit money around since it's usually cash transactions with strangers. So does anyone use one of those "counterfeit detector" pens to make sure the bill is genuine?

Except I've heard that there are now some sophisticated counterfeiters who make bills that will pass the "pen test".
