France, 1790 - 1793

Jeannetty was paid L.T. 10.542/Ozt sometime around 1793.  Assuming his platina was 70% Pt and without calculating the refining cost, 

1793: 1 Troy Ounce platina (ore) = L.T. 10.542
1793: 1 Troy Oz. Pt (.999 Ore) = L.T. 15.06

The French Government purchased 75.038 Kgs of platina for Fr. 8,895

1791-1793: 1 Troy Ounce platina (ore) = L.T. 3.687
 
Assuming a par value 'Franc'/Livre, the French government price paid for platina 1791-93 was rather low:

1791: 1 Troy Ounce platina (ore) = Fr 8.13 (USD$ 1.60)

1792: 1 Troy Ounce platina (ore) = Fr 9.14 (USD$ 1.50)

1793: 1 Troy Ounce platina (ore) = Fr 7.88 (USD$ 1.69)

"real or apprehensive; at the same time, everything bought by foreigners, or which can be bought by them, has risen greatly; for instance, the cloth of Abbeville, a French commodity, has risen from 30 livres to 42 livres the aulne"

In 1790, at "45 L.T./Ell" and 1 Livre = £ 0.0365 ∴ 1 English Yard of 'Peignon' cost 37.098 - 39.57 L.T. (=£ 1.354 - 1.44)  

In May 1794, when '24 Livres' cost Fr 50. - 55., an Ell of 'Peignon' cost 3 Louis (£ 2.85)
∴ 1 English Yard of 'Peignon' cost Fr 123.66 - 131.90 (=£ 2.35) ; Fr 56.14 = £ 1.




Had the May 1794 Paris Price of manufactured Platinum likewise risen 62.63% from 1790,
