|Nicholas I (1825-1855)|
A profoundly original phenomenon was the striking by the Russian state of new platinum coins with the value of 3, 6 and 12 rubles from 1828 to 1845. Russia is the only country in the world that struck platinum coins for circulation. Shown is a 12 rubles piece, 1830, with inscription proclaiming this coin to be composed of nine parts gold and sixty-eight parts of “pure Urals platinum”.
