By 1806, the availability and price of Wollaston's Platinum was announced in Germany & Continental Europe. (This English Price assumes an exchange rate of 1 Rthlr. = £ 0.20 ; w/o shipping, insurance, tariffs, etc.)
1805- 1 Troy Oz. Platinum (manufactured, retail) = £ 0.75 - 0.9o (Thlr 4.)
Citation: Annalen der Physik, 1806 Vol. 19-24 V p.231
Where 1 Loth = 225.5 grains = 0.4867 Troy Ounce, and if this is an accurate quote, the earlier presumed imported German price was nearly double the 1818 Paris price.
Although this is closer to Knight's contemporary price in 1800, 36 Francs is suspicious close to the French Once price in 1811 (seven years before the article's date.) Other German sources (c. 1825) reference astronomical prices, perhaps from this period.

Dubious (historical) Paris Price, suspect typographical error:

Citation: Morgenblatt für gebildete leser, Volume 13 (1819) p.20
Foreign Exchange (August, 1804) : 1 Rthlr = £ 0.225 = Fl. 1.50
1806: 1 Troy Ounce platina (Cartagena: Spot-Price) = Fl. 1.
1806: Spanish & USD$ ($1) to Rheinish Gulden:
1806: 1 Troy Ounce platina (Cartagena: Spot-Price) = Fl. 1.
1801- : Jeannetty's address above the Hotel de Boston,
This is so far the only one which, deals with the processing of platinum in Paris, and both at home and abroad sent his skillful work. *) On all instruments
