Where Platinum Foil was sold at $10./oz, an Ounce of Platinum Chloride was nearly double the price.  But these trade prices seem impossibly low, half the market-price for Platinum ingot and below the Russian source prices.

November, 1906: 1 Troy Oz. Platinum (Semi-Mfg, Foil, 50%?) = USD$ 10. -16.

November, 1906: 1 Troy Oz. Platinum Chloride (PtCl₂, 29%? Ret.) = USD$ 18.50

Chlor-platinates

c.1859: Double Salt, at 28% purity



By fluid volume, there were 0.44 - 0.88 English Troy Grains pure Pt per Imperial fluid ounce of bichloride solution



 26.5% Pt

UK, 1859

Refiners undoubtedably reaped greater savings with discounted bulk purchases or contract prices far lower than 'common prices.'  In 1859, Platinum still sold at the same 1850 wholesale price, strongly suggesting source- and spot-price stability.

Assuming a Price/Weight set by Specific Gravity of 21.5, a kilogram of Russian scrap, large bulk, cost £ 24.90 -26.00 and sold £ 40., a 62% markup.

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

1859: 1 Ozt Platinum (SPb, Bulk Refined) ~ £ 0.9283 - 0.9701
1859: 1 Ozt. Platinum (SPb, Same, Cash-Rate) ~ £ 0.8947 - 0.9127

1859: 1 Ozt. Platinum (UK Mkt: Scrap?) =                          £ 1.25 (USD$ 6.13)
1859: 1 Ozt. Platinum (UK Mkt: Producer?) =                   £ 1.50 (USD$ 7.35)

1859/60: 1 Ozt. Platinum (Intrinsic, Bulk) =                     £ 1.35 (USD$ 6.62)

1859/60: 1 Ozt. Gold (Intrinsic, Common) =                     £ 3.66 (USD$ 17.92)

April 1860: 1 Ozt. Platinum (Refined, Retail) =               £ 1.60 (USD$ 7.11) 

Oct.? 1860: 1 Ozt. Platinum (UK Mkt: Assumed) = £ 1.35 ($ 6.57)

March, 1859:

a 2"x6" (12 sq. in, 24 sq. in of surface) sheet Platinum cost ~£ 0.35 (~0.22 Ozt) 47% of the Grove-Styled 20-Cell described by Wylde.  Each Cell would presumably hold .6 sq. in. (1.2 sq. in. surface) Platinum, about 5.3 Grains Troy per Cell.

Very Thin Sheets:  ~£ 0.029167 per sq. in. Pt and 54.86 Sq In. Pt (109.71 Sq. In.) per Ozt.
