Grivna
As its etymology implies the word originally meant a necklace or a torque. The reason why it has taken the meaning of a unit of weight is unclear. The grivnas that have been found at various archaeological sites are not necklaces but bullions of precious metals, usually silver. The weight and the shape of grivnas were not uniform, but varied by region. The grivnas of Novgorod and Pskov were thin long round-edged or three-edged ingots, while Kievan grivnas have rather the shape of a prolonged rhombus. The material was either gold or silver, but silver was predominant. Originally the weight of a grivna was close to the Roman or Byzantine pound. The weight of the Kievan grivna was around 140–165 g (0.309–0.364 lb). The Novgorod grivna had the weight 204 grams (0.450 lb) and became the basis for monetary systems in northeastern Rus', including the emerging Grand Duchy of Moscow.
