After technological attempts to exploit the recalled Platinum coinage from the State coffers had been abandoned - for a Russian industry for Platinum manufactures did not exist - in 1857 654.4 kilograms (of Platinum, as Scrap) were sold for 215 Roubles per kg to the Paris refinery of Desmoutis.  In 1862, Johnson, Matthey & Co. of London took a further 11,800 kg at the price of 199 Roubles per kg. With this large supply, the English company was able to secure a world monopoly of trade for many years.  Prices for Russian crude platina, the refined metal and other PGMs hereafter rose or  fell according to the English market.

1862 Platina Yield: 142.025 Poud = 5,681 Funt = 74,796.72 Ozt. = 2,326.44 Kgs.
1862 Platina Export: 49 Poud = 1,960 Funt = 25,806 Ozt. = 802.65 Kgs.
