Spain, 1808
Citation: Platina española para Europa en el siglo XVIII, LF Capitan Vallvey (1994)
"The French invasion of 1808 causes the destruction of Madrid's Casa de Platina, the disappearance of all the metal stored there, and independence of New Granada a few years later (in 1819) leaving Spain without possession of the platina mines."
1793
Jeannetty was paid L.T. 10.542/Ozt sometime around 1793. Assuming his platina was 70% Pt and without calculating refining cost,
c. 1793: 1 Troy Ounce platina (Est. 70% ore) = L.T. 10.542
c. 1793: 1 Troy Oz. Pt (.999 Ore) ~ L.T. 15.06
1793: 1 Troy Oz. Pt (Paris Labor, 1789) = L.T. 30.47 (S$ 7.92)
1793: 1 Troy Oz. Platinum (Paris First Base Cost) = L.T. 45.53 (S$ 11.83)
Although this may have been intercepted Spanish cargo (or ~two strong-boxes) of platina, it is more likely ore requested from and paid to the Casa de Platina directly @ ~3 Reals per Onza, a wholesale import European price.
The 1795 Paris price was known to be L.T. 81.4034 ; Janetty's higher price appears to be retail.
25/5/1793 : 226.375 Marcs = 1,781.345 Ozt (55.406 Kgs.) ∴
Where 1 Paris Marc cost L.T. 12 (S$ 3.12) apparently from the Spanish Crown,
226.375 Marcs (120.4425 Libras) cost L.T. 2,716.50 (5,646.76 Reales), so
1 Libra cost 46.88 Reales (S$ 5.86 ; L.T. 22.55), or at the Spanish Onza (0.9243 Ozt),
1 Onza cost S$ 0.3663 (2.93 Reales) x 1,927 Onzas = S$ 705.84
1793: 2.93 Reales/Onza = 46.88 Reales/Libra = S$ 5.86 at Madrid delivered to Paris.
May 1793: 1 Troy Ounce platina (Spanish Crown) = L.T. 1.525 (S$ 0.40, R. 3.17)

Although
not specified as such, Priestly's price-weight is entirely consistent
with platina ore at avirdupois. Where 8 ounces avd = 7.292 English Troy
Ounces,
"Richard Knight and His Production of Malleable Platinum"(PMR Vol. 29, #1, 1985; p. 30)
Priestley was also sufficiently interested in platinum to purchase a modest amount; his claim for compensation after the destruction of his house and laboratory on July 14, 1791 includes the item “Half a pound of platinum £ 2 8 s. 0 d.”
c.1790/1: 1 Troy Ounce of platina (ore) = £0.33
c. 1917 anecdote. A full-weight 1789 2-Escudo weighs 6.76 g., .8985 Fine Au
The Specific Gravity for an older true 2-Escudo should have been 17.655, or 17.18 for a coin just .875 Fine Au. Also, given the loss of weight from wear, the original Platinum forgery 'new' likewise should have had a Specific Gravity ~19. At this SG, the counterfeit would likely have been approx. 5% Au (Surface), 90% Pt and 5% Cu

"The price {of Platinum manufactures} is slightly lower than works in gold."

You
unquestionably have long known that some excellent chemical artist edit
the Platina as other metals, even found time not so long ago: but that
work had been so multiplied darinn now, you would think no. Meanwhile, I
can still assure you that at Janety - of against very cheap prices
includes snuff-boxes, watch chains, spoon, toothpick boxes,
Löhtröhrchen, and everything you could want from a similar work only
wishes and orders, (Marchand Orfevre, Rue de l'Arbre Sec) pure platinum,
extremely clean and tastefully worked once can get. The Preiss of
commodities depends, like, gold and silver, according to the severity
and type.

France, 1801
1793: 1 Troy Oz. Platinum (Paris First Base Cost) = L.T. 45.53 (S$ 11.83)
Fall 1795 - Fall 1801: 1 Troy Oz. Pt (Mfg Cost, Estimate) = Fr. 15.2361 / 15.238
Fall 1795 - Fall 1801: 1 Troy Oz. Pt (Mfg: Actual Cost) = Fr. 31.102
The total weight of the final delivered Platinum product (4 Meters, 4 Kilograms) should have been ~416.603 Ozt (~12.96 Kgs) ; the weight of Kilogram known, the Meter is presumed 72 Ozt.
Jannetti was actually paid Fr. 12,922.10 for the eight (8) items.
1.The first Meter & Kilogram required 136.846 Ozt Platinum (Assume: for the Metre ~92.25 Ozt, for the Kilogram 44.6 Ozt) (~28.13% wastage on the Meter; ~38.72% wastage on Kg.)
2. Second Meter required 90.08 Ozt (~25.11% wastage on 2nd Meter)
3. The first Meter was reworked, + 8.861 Ozt (~40.43% wastage on 1st Meter
4. Second Kilogram required ~36.92 Ozt (~14.83% wastage)
5. Third Kilogram required ~37.90 Ozt (~17.89% wastage)
6. Third Meter required 85.406 Ozt (~18.62% wastage)
7. A Kilogram was reworked, ~44.303 Ozt (~37.8% wastage)
8. Fourth Meter required 80.85 Ozt (~12.3% wastage)

c.1799: by fusing with metallic arsenic, Jeannetty's Platinum was probably ~1% metallic Arsenic, 7.2% Iridium and 91.8% Platinum or 1.10% As, 13.8% Ir and 85.10% Pt
