All counterfeits of any coins or obligations or other securities of the United States or of any foreign government, or any articles, devices, and other things made, possessed, or used in violation of this chapter or of sections 331–333, 335, 336, 642 or 1720, of this title, or any material or apparatus used or fitted or intended to be used, in the making of such counterfeits, articles, devices or things, found in the possession of any person without authority from the Secretary of the Treasury or other proper officer, shall be forfeited to the United States.

Whoever, having the custody or control of any such counterfeits, material, apparatus, articles, devices, or other things, fails or refuses to surrender possession thereof upon request by any authorized agent of the Treasury Department, or other proper officer, shall be fined under this title or imprisoned not more than one year, or both.

Whenever, except as hereinafter in this section provided, any person interested in any article, device, or other thing, or material or apparatus seized under this section files with the Secretary of the Treasury, before the disposition thereof, a petition for the remission or mitigation of such forfeiture, the Secretary of the Treasury, if he finds that such forfeiture was incurred without willful negligence or without any intention on the part of the petitioner to violate the law, or finds the existence of such mitigating circumstances as to justify the remission or the mitigation of such forfeiture, may remit or mitigate the same upon such terms and conditions as he deems reasonable and just.

If the seizure involves offenses other than offenses against the coinage, currency, obligations or securities of the United States or any foreign government, the petition for the remission or mitigation of forfeiture shall be referred to the Attorney General, who may remit or mitigate the forfeiture upon such terms as he deems reasonable and just.
