Palladium from the country that mines it
The USSR produced most of the world's palladium (Norilsk still does today) and in 1989, with hard currency scarce, began striking it into 25-ruble bullion coins celebrating Russian ballet. The Moscow and Leningrad mints continued the series through the collapse of the Soviet Union, changing the state emblem on the obverse in 1992 but keeping the ballerina.
