Barbor Silver and Silver Plate in General

By International conventions all items made of precious metals such as silver in Europe and
North America carry marking to indicate their level of purity, such as the word "Sterling",
numbers such as " 925" ( 925/1000 parts pure), "800" ( 800/1000 parts pure) or stamped
markings referred to as " Hall Marks" that indicate the date made, the maker, city of origin
and metal content. The lack of any such markings indicates this set is most likely silver plated.
