Interesting, threadkiller. I ate brunch at a cafe last weekend and saw the lady behind the counter inspecting three $100’s. I asked her if she gets a lot of counterfeits and she told me that she’s been in business 15 years and had never received one until last year. Since then she’s gotten three. She wasn’t even sure if they were real. She had the pen out, marked them up, looked at them in the light, then asked me if I thought they were real or not. I told her I’m no expert but they looked real to me. Seems to me a retail business should be educated on these things. A new $100 was recently released: http://www.newmoney.gov/newmoney/Splashpage.aspx
