Precious metals are subject to great scrutiny from lawmakers because of their financial and strategic importance. Gold and silver coins have been hallmarked since ancient times but the platinum group metals (pgm) were only known from 1748, therefore their hallmarking and fineness control is more recent. This paper reviews the legal history of pgm control in Switzerland where precious metal refiners’ and fine watchmakers’ lobbying impacted Swiss regulations on precious metals trade. Platinum and palladium have been regulated since 1914 and 1995 respectively while the other pgms (rhodium, iridium, osmium and ruthenium) are not.
