William Sturgeon's Fifth Memoir was composed in 1839, so his prices must date from that year. As a Grove's Battery of 10 Elements cost £ 7.0, a single Grove's Element cost £ 0.70 w/ 1 o.5"x 4" = 2" Sq. Foil. Where 50 pairs Platinum Plates 4"(o.5"x 4" = 2" Sq., double-sided = 4" Sq.) = 100 Sq. In.; 1 Grove's Battery (10 Pair) = 20 Sq. In.; 1 Element created .5 Cu. In. gas per minute.

USA, 1833

Dr.? Erastus F. Cooke of Wethersfield, CT (close to Hartford) reported European Platinum Still prices from the Spring of 1833.

The Kepp platinum still held 136.383 liters; where boiler and syphon was £ 598.50 was taken at the USD was taken at a Silver Rate of 45.77 (USD$ 3,138.) ; at the Paper rate 54 pence, $2,660. This assumes Troy weight (495 ozt) but excludes any additional tariff, shipping & handling cost to New York.  Importation duty of boiler plates in 1833 apparently added 25%, plus any additional local delivery charges to the buyer. Unknown freight, insurance, etc: +5%?  Estimated NYC trade profit on a British still at the Paper rate, and competitive with reported French price plus duty = ~$247.50 or ~9.3% UK Price.

1833: 1 Troy Ounce Platinum (UK Mfg) = £ 1.20909 (USD$ 6.34; $5.37)  
1833: 1 Troy Ounce Platinum (NYC: Mfg +30% Cost) ~ £ 1.572 (USD$ 7.)  
1833: 1 Troy Oz. Platinum (imported Paris mfg @ NYC)  = USD$ 6.00  
1833: 1 Troy Oz. Platinum (NYC: Paris mfg still, w/duty)  = USD$ 7.50

Austria, 1871

In 1871, Russian platina from Tagilsk was indicated as 75% Pt, 1.1% Pd, 3.5% Rh, 2.6% Ir, Os-Ir 0.6%, 2.3% Os, 0.4% Au (15% other) with 9.4% of the PGMs held by the refiner as cost.  Where the Zollpfund is 500 g., 1 kg Russian Pt (at purity) cost Fl 302.90 in Europe. 

1871: 1 Troy Ounce platina = Fl 7.066  (Fl. 6.90, Fr. 15.10, £ 0.566 ~ USD 3.09)
1871: 1 Troy Oz. Pt = Fl 9.42  (Fl. 9.20, Fr. 20.14, £ 0.755 ~ USD 4.12)

1871: 1 Troy Oz. Platinum (Paris mfg, bulk) = Fr 23.33 (USD$ 4.77) 
  

1871: 1 Troy Oz. platina (London, bulk) ~ £ 0.925 (USD$ 5.05)
1871: 1 Troy Oz. Platinum (UK: semi-mfg, retail-trade) ~ £ 1.65 (USD$ 9.00)

1871:  1 Troy Oz. Platinum (USA: imported, mfg, trade) = $ 5.50/ USD$ 6.13
July 1871: 1 Troy Ounce Platinum (USA: semi-mfg, retail-trade) = $ 8.61/ USD$ 9.60 

 
Das rohe Platin wird von den Privaten meist nach England und Frankreich verkauft, wobei man pro Zollpfund reines Platin 151 fl. 45 kr. österr. W. zahlt; die anderen Metalle werden nicht vergütet. Die 1828 begonnene Prägung von Platinmünzen ist 1845 in Folge des bedeutend zurückgegangenen Handelswerthes des Platins eingestellt. Zur Hebung der Platinproduction hat die Regierung Erleichterungen im Raffiniren, in der Besteuerung und im Verkauf des Platins gewährt. 

The crude platinum is sold by the private sector, mostly to England and France, paid at the rate of 151.45 Florins Austrian W. per Zollpfund of pure platinum; the other metals will not be reimbursed. The coining of platinum began in 1828 and ended in 1845, as a result of significantly lower trading valency of platinum.  A rising standard of platinum production, the government has granted concessions in the refining, taxation and sale of platinum.

c.1847: 1 Troy Ounce platina (Ore: 85.9% Pt)= Fl 9.9815 (Thlr. 5.70; ℳ 11.27, ) 
c.1847: 1 Ozt. Pt (at purity) = Fl 11.62 (Thlr. 6.64; ℳ 13.12)

Enhanced treatment for processed platinum is so difficult the refined price is double raw platina. But it costs a pound of raw platinum approximately Fl. 180 and the values ​​of silver, platinum and gold behave almost as 1: 3: 5 Besides the chemical-ware, jars, bowls, retorts and distillery apparatus for sulfuric acid plants...
