France, 1837: Various Prices Cited, most Dated?

Prof. Hagen has shown in Pölitz's Jahrbucher (Jan. 1830) that it is not for this purpose in Europe; the coinage costs are 37% of value. In modern times the price has been much lower than before; the French ounce costs Fr. 22 in Paris, while it costs Fr. 30 in former times."

c.1837:


The wholesale price of Platinum fell -55% in ten years, from 1828 - 1837.

1828: 1 Troy Ounce Platinum (France Wholesale Price)  = Fr 34.21

1836/7: 1 Troy Ounce Platinum (France Wholesale Price)  = Fr 15.

The estimated Russian price (Fr 2,000./kg) appears to calculate the Silver Rouble rate, rather than the Paper Rouble rate.

c.1837/8:  Russian platina cheaper than Colombian platina.
Rohes amerikanisches Platin, ganz auf dieselbe Weise wie reiner Platindraht behandelt, gab eine Flüssigkeit, mit der man ganz gut platiniren konnte. Auch Platin vom Ural, dem noch mehr als dem andern fremden Metalle beigemengt ist, und das noch weniger kostet, auf dieselbe Weise in Chlormetall verwandelt, diente eben so gut zum Platiniren der erwähnten Metalle.
