Re: Craigslist Scam???
It is not the cops, it is the Secret Service or FBI that will respond to this. Both operate out of the Treasury Department who are in charge of this stuff. Passing counterfeit is a federal problem and IF "the bank" actually caught a counterfeit bill, they have filed a paper trail that the feds can verify.
If your money was not counterfeit and someone is swapping in counterfeit in order to pass it, that will still get their attention.
If you use cash, you run the risk of losing it that way. Banks are required to confiscate counterfeit, and that's simply your loss.
Now, is the other guy playing games with you? Good question, start by calling in the feds and telling them you trust the source you got your bills from (hopefully, a bank teller) and that you think someone is running a scam.
Meanwhile...If you didn't get those bills from a trustworthy source, you've got a problem.
