An English arithmetic from 1861.

Suisse, 1838

Presumably calculating in the Swiss fluid ounce (not an English ounce, nor the long since abandoned Paris once)  Dr. Melly in Geneva assumed '1 once = 27cc' so "15 once de l'eau" is 405 cc (or 13.69 US fluid ounces, 14.25 British Imperial ounces.) 

By volume, a 400 cc dish weighed about 105 g; a platinum vase of 3.3735 Ozt. for "at least" Sw.Fr. 200 implies a very high cost (import duty?) exaggerated:

c.1836: 1 Troy Oz. Platinum (Mfg, Ret) = Sw.Fr Sw 59.29 (USD$ 11.16)

At nearly 1/10th the price, the plated manufacture (w/ 14 g platinum) would cost just SwFr 30, all labor and materials.

USA, 1868-75: Investogation of Chemical Markups

The retail charge to University of Michigan students was 40-60% over currency rates, but as high as 300% for some rarer chemicals & reagents.  It is entirely reasonable to assume that Platinum (among the rarest elements) was also subject to the high mark-ups.  


Clearly, the retail price charged was much, much higher than wholesale catalogue prices.

USA, 1892: Retail Cost (Reference)

1892: 1 Troy Ounce platina (Colombia: Ore, Export) ~USD$ 12.90
1892: 1 Troy Oz. Pt (Colombia: Ore, .999) =~USD$ 15.63  

Retail receipts for refined Platinum products most nearly approximate retail investor cost.  Price comparisons in relation to this 1892 NYC Importers' Catalogue indicate the retail cost was ~33% higher than wholesale products in the same year.

Where "2 Plain Crucibles, 15 cc 34.4 gms" weighed 17.2 g./ea., and "4 Crucibles platinum, 15 cc, plain, 11.15 gms" weighed 11.15 g./ea., the difference 6.06 g ought to be the Cover.; consistent with Catalogue explanations, the Cover ought to be ~35% of the total weight.

 Where Platinum Crucibles cost $0.65/Gram:
1892: 1 Ozt. Platinum (Mfg, Ret.) = USD$ 20.22 

1892: 1 Troy Ounce platina (Ore, Retail) = USD$ 16.46
 

1892: 1 Ozt. Platinum (Scrap, Ret.) = USD$ 15.55

1892: 1 Ozt. Platinum (Foil: Semi-Mfg, Ret.) = USD$ 18.66

1892: 1 Ozt. Platinum (Mfg, Ret.) = USD$ 20.22 - 27.90
