From 1820 (?) - 1840, the Paris market price of Platinum notably rose +40%. It's unclear exactly when the refined semi-manufactured retail price was Fr 20.32.

1839: 1 Troy Oz. platina (Russian ingot) ~ Fr 15. - 16. (USD$ 3. - 3.20)

Citation: Éléments de l'économie politique; Joseph Garnier (1846) p.140

c.1839/40: Referring to Russia's Platinum coinage in the present tense. The reference to periods of lower Platinum prices likely refers to 1830-1 and 1815-20 (although this young chemist would have known this only by hearsay.)
