Ask a Lawyer and Get Answers to Your Legal Questions
Unfortunately, there is only one thing to do, unless you want to get into a lot of very serious trouble:
1. Contact the seller, and offer to return the merchandise, or alternatively pay for it with real money.
2. Contact the United States Secret Service field office, immediately.
If you don't do the foregoing, you could be charged with a federal felony offense of passing counterfeit currency.
