18 U.S. Code § 472 states that “Whoever, with intent to defraud, passes, utters, publishes, or sells, or attempts to pass, utter, publish, or sell, or with like intent brings into the United States or keeps in possession or conceals any falsely made, forged, counterfeited, or altered obligation or other security of the United States, shall be fined under this title or imprisoned not more than 20 years, or both.” Thus, if acting in good faith without intent to defraud, individuals who report suspected counterfeit currency to authorities will not be held legally responsible if the note turns out to be counterfeit.
