My friend sold his Glock 23 today and when he tried to deposit the money, he found out that what he got was 5 real $20 bills wrapped around 20 really good fakes. Someone bleached $1 dollar bills and reprinted 20s over them. He used a counterfeit pen, but since the paper was real, it didn't give the buyer away. He went to the police with the guys name, address and phone number, but they said since he couldn't prove he got the money from the dude, there was no case. So... he sold his Glock for $100. Just a heads up, the police said that this is happening everywhere lately.
