The Russian standard for silver was based on ' zolotnik '. The name comes from 'zoloto' meaning gold. The unit originated as the weight of a gold coin of the same name which circulated as late as 11th century in Kievan Rus. Originally, a zolotnik represented a 1/96 of a pound, later 1/72 of a pound. In the metric system, one zolotnik equals 4,266 grams, 96 zolotniks equal one Russian pound.
Converting the Russian marks to sterling values, we obtain the following comparisons in silver purity degree:

Most of silversmith's touch marks are in cyrillic alphabet.
