(b) Articles made in whole or in part of gold or silver or alloys thereof imported for sale by manufacturers or dealers which are marked or labeled in a manner indicating a greater degree of fineness than the actual fineness of the gold or silver or alloys thereof, and any plated or filled articles so imported which are marked or labeled to indicate the fineness of the gold or silver and are not also marked or labeled to indicate the plated or filled condition or are marked or labeled with the word “sterling” or the word “coin”, are prohibited importation and shall be detained, and the facts shall be reported to the United States attorney.
