Recently acquired an 1883 Russia ruble as part of a collection.
See example here:
https://www.ngccoin.com/price-guide...duid-1538611Condition is F/VF. Color and details look right, non-magnetic, passes the ping test, but coin is overweight.
Per NGC, coin should be 20.73 gams
Wondering what is an acceptable tolerance for weight variation on these or similar rubles from that era?
