Russia, 1859

Where 1 Poud (= 3,840 Zolotnik) = 2,941 руб Kr. (1859) and 1 English Troy Ounce = 7.2914432 Zolotnik, the Funt (presumed by 'fine,' by Specific Gravity 21.5) cost £ 10.19 - £ 10.65 at prevailing exchange.  Poud rates were for un-worked ore, at assumed Fine rates.*

1857: The cost of '1 kg platina' (@SG 21.5) 181.77 руб Kr. + Assumed Refining Cost (35 руб Kr.) = ~217 руб Kr./kg. (+ Duties?) = 6.75 руб/Ozt. (~ -30% lower than the 1828 Price)

*At SG 20, a 'kilogram of raw, assumed platinum' in ore sold much much lower; actual mass of the raw platina varied considerably, containing other PGMs.  For example, worked ingot Platinum was assumed 21.35 in 1835. If Ural platina was just 81.5% those metals (Pt, Ir, Au) to that SG, or ~ 80% - 80.5% pure Pt.  So ore merchants must have adjusted accordingly: to produce 1 kg. Pt @ .999 actually required ~1.25 Kg of Ural Ore (.805 Fine Pt).

1857:  1 Ozt Platinum (SPb: Scrap .95 Pt, Very Lg. Bulk) = 6.687 руб Ag. (£ 1.03) 

1859: 1 Troy Ounce Pt (SPb, Bulk Ore) = 5.5844 руб Kr. (£ 0.7737 - £ 0.8086 )
1859: 1 Ozt. platina (SPb, Bulk Ore) = 4.6630 руб Ag (£ 0.745 - £ 0.760 )

1859: 1 Ozt Platinum (SPb, Bulk Refined) ~ 6.70 руб Kr. (£ 0.9283 - 0.9701)
1859: 1 Ozt. Platinum (SPb, Bulk Ore) ~ 5.60 руб Ag (£ 0.8947 - 0.9127)


1862:  1 Ozt Platinum (SPb: Scrap .95 Pt, Very Lg. Bulk) = 6.1842 руб Ag. (£ 0.8947)
