Silver hallmarks have been used in Norway since the sixteenth century. In 1891 a national system was established that is still in use today. The current system requires only a silver standard mark accompanied by a makers mark. The old Norwegian standard of .830 silver purity is still used but beginning about 1920, the .925 silver purity began replacing it and is now the foremost standard used. The letters NM are sometimes seen on flatware, the abbreviation is an indication of a design patent or copyright.
