"With the introduction of platinum coins in 1828, the assumed metallic value was 1.236 руб per Zolotnik, or 4,746 Roubles per Poud. As a result, this nominal value differs so greatly from the commercial value of the metal; under such circumstances, in 1843 the Treasury took the question to council whether to continue minting Platinum coinage. In 1844 the difference was already calculated at 137% (3,464 Roubles per Poud) and in 1845, as revealed that in the main markets (Paris, London, Hamburg) it was officially retracted that prices were fluctuating between of 2503-2808 Roubles per Poud. So instead of 1.236 руб per Zolotnik, the cost was only 0.65-0.74 руб and the government was induced, following on 9 February 1845 to meet the most supreme confirmed measures:"
