Typically, Russian silver coins mention a weight on the edge e.g the poltina 1832-1858 has:
СЕРебряный 83 1/3 ПРОБЫ 2 ЗОЛотни́к. 41 7/25 ДОЛя.
Silver 83 ⅓ (0.8333 fine) proof 2 Zolotnik 41 7/25 Dolia.
There are 96 dolia in a
zolotnik; a dolium is 0.044 grams and a zolotnik is 4.2658 grams. The weight given therefore translates to about 10.3479 grams.
The rouble's edge says:
СЕР∙83 1/3 ПРОБЫ 4 ЗОЛ∙82 14/25 ДОЛИ
So it is the same fineness, but exactly double the weight of the poltina.
In Soviet times, the edge of the rubels of 1921 and 1922 says:
ЧИСТОГО СЕРЕБРА 4 ЗОЛОТНИКА 21 ДОЛЯ
Pure silver 4 zolotniks 21 dolia. The first communist ruble is in fact 0.900 fine and at 17.987 a tad lighter.
The notation was discontinued after 1922 as a consequence of hyper-inflation.
