1883: 1 Troy Oz. Platinum (Ore, at purity) =USD$ 5.49
c.1882/3: 1 Troy Oz. platina (California: Spot, ~52-60% Pt) = USD$ 0.75
c.1882/3: 1 Troy Oz. platina (California: Spot, Intrinsic) = USD$ 1.25 - 1.44
1883: 1 Troy Oz. platina (CA ore ~52-60%, NY Spot) ~ USD$ 2. - 3.
1883: 1 Troy Oz. platina (CA ore Intrinsic, NY Spot) ~ USD$ 3.33 - 5.77
1883: 1 Troy Oz. platina (Export: CA ore, ~52% Pt) ~ USD$ 2. - 3.
1883: 1 Troy Oz. platina (Export: CA ore, .999 Pt) ~ USD$ 3.85 - 5.77
c.1882/3: 1 Troy Oz. platina (CA: Spot, ~21% Pt, 73.5% Os-Ir) = USD$ 0.75

California platina were recorded as low as 19-28% Pt, though some 'poor samples' may have included 30-52% Iridium (both Pt & Ir have relatively high specific gravities, 'poor samples' probably meant < 54% of either) Platina from Trinity River, for example was ~ 21-29% Pt. Considering all the PGMs present in California ore, where Platinum sold commercially for $6.50, Iridium $18., Osmium $45. and Rhodium $40. the true intrinsic value of a kilogram of a 'less pure' sample California platina may be seen.
45% Pt, 25% Ir, 22% Os, 8% Rh:
California Spot (CA platina) = $24. per kilogram
New York Spot (Export: CA platina) = $64. - 96. per kg.
New York Spot (Imported Refined PGMs) = $660.
1883: 1 Troy Oz. Platinum (NYC: imported,unmfg) = USD$ 6.50 - 7.50
1884: 1 Troy Oz. platina (NYC: US crude) ~ USD$ 4.00
1884: 1 Troy Oz. platina (NYC: US crude, Export) = USD$ 5.00
1884: 1 Troy Oz. Platinum (Scrap, Bought) = £ 1.10 (USD$ 5.34)
The very low quality of Northwest platina, noted.

In the pre-War period, refiners typically did not compensate platina sellers (miners or source middle-men) for other PGMs.

From The Fourth Annual Report of the State Minerologist 1884 (California), the high cost of mining and low return on platina explains local disinterest.
