A single official hallmark will be used for all precious metals and all fineness standards, the "head of a St. Bernhard dog":

The official controlling (conformity testing) of articles made entirely of certified materials is less costly than the controlling of articles of unknown origin. The Ordinance on the Collection of Fees and Supervisory Levies for Precious Metals Control (PMC-FeeO; SR 941.319) takes this fact into account by granting a reduced fee for conformity assessments for articles made of certified materials (Art. 6 and Annex no. 1 PMC-FeeO).
