What country coined platinum money?

In 1828 the Russian government began the coinage of platinum money. Platinum was produced in considerable quantities in the Ural Mountains’in Russia and its general scarcity and great value were not at first appreciated. For many years the Russians considered the metal of such small value that peasants used pots and pans made of platinum to cook then: meals. Swindlers, it is said, used to cover platinum bricks with gold plate to sell them as gold. Between 1828 and 1845, when the Russian government abandoned such coinage, platinum coins worth more than $1,300,000 were struck off in denominations of one, three, six and twelve rubles. These coins contained about two per cent of the rare, metallic element known as iridium, which resembles platinum but is harder and brittle. Platinum, then worth about a third as much as gold, proved unsatisfaqtory for monetary purposes for several reasons. The metal resembles several metals of slight value and is -easily counterfeited. Its high melting point made it expensive to mint. Besides platinum is subject to sudden fluctuation, in value. Soviet Russia tried platinum coins in. 1930 but soon abandoned them for similar reasons: The French government at one time used platinum as an alloy to harden gold and silver coins. During a period of about thirty years the price of platinum jumped from $16 to $105 an ounce and the French government replaced the platinum coins to recover the valuable metal. Platinum is extremely malleable and ductile; a troy ounce of the metal can be stretched into a wire more than ten thousand miles long.
