Russia, 1825

1825: 1 Troy Ounce platina (SPb: Ore 80%) = 7.1625 руб Acc.

  The first buyer was the government. From the years 1825-1843 the delivery of the whole platinum gained to the Crown was required. The price paid was initially (1822?) 60 Kopecks per Zolotnik, or {140.66 руб Acc.} per kilogram, with 10 to 12% deducted by the assayer {123.78 руб Acc., net}.  Three years (1825?) later, it rose to {230.31 руб Acc.} per kilogram and finally the coining period (1828-1843) to {290.25 руб Acc.}

From Russian sources, Iridosmine was discovered (1824) and identified by 1825.  Laugier estimated the Russian platinum ingot to be 80% pure Pt, 14.44% platina-black and ~6% other metals/slag. 

The best quality ore was 86.5 - 88% Platinum, the standard ~73.6 - 78.9% and the lower quality ~70% by 1834.



In June 1825, Russian-manufactured bar-platina was initially described 65% Pt, 20% Ir and 15% Other (9% Ir, 4% Os, 2% Other?)
