Prior to 1795:
Where 32 Reales = L.T. 15.30, S$ 1 = L.T 3.83, and 10 Arrobas = 1,879.527 Paris Marcs
∴ 16,000 Reales = S$ 2,000.; L.T. 7,650, so 1 Paris Marc cost L.T. 4.07; S$ 1.064097
1795: "4 Reales/Onza" = 64 Reales/Libra = S$ 8. at Chocó?
At the Spanish Onza (0.9243 Ozt), 4 Reales = S$ 0.50 x 16,000 Onza = S$ 8,000.
∴ 64,000 Reales = L.T. 30,600, so 1 Paris Marc cost L.T. 16.2807; S$ 4.2564
Highest estimates follow the presumed Chocó Base-Spot, largely consisted with recorded price differentials between trade points in 1802, 1814, and 1818.
c.1795: ~"8 Reales/Onza" = 128 Reales/Libra = S$ 16. at Cartegena
At the Spanish Onza (0.9243 Ozt), 8 Reales = S$ 1.00 x 16,000 Onza = S$ 16,000.
∴ 128,000 Reales = L.T. 61,200, so 1 Paris Marc cost L.T. 40.70; S$ 8.513
c.1795: ~"10 Reales/Onza" = 160 Reales/Libra = S$ 20. at Jamaica
At the Spanish Onza (0.9243 Ozt), 10 Reales = S$ 1.25 x 16,000 Onza = S$ 20,000.
∴ 160,000 Reales = L.T. 76,500, so 1 Paris Marc cost L.T. 32.5614; S$ 10.64
c.1795: ~"12 Reales/Onza" = 192 Reales/Libra = S$ 24. at Philadelphia
At the Spanish Onza (0.9243 Ozt), 12 Reales = S$ 1.50 x 16,000 Onza = S$ 24,000.
∴ 192,000 Reales = L.T. 91,800, so 1 Paris Marc cost L.T. 48.8421; S$ 12.77
c.1795: ~"18 Reales/Onza" = 288 Reales/Libra = S$ 36. at London
At the Spanish Onza (0.9243 Ozt), 18 Reales = S$ 2.25 x 16,000 Onza = S$ 36,000.
∴ 288,000 Reales = L.T. 137,700, so 1 Paris Marc cost L.T. 73.2632; S$ 19.15
1795: "20 Reales/Onza" = 320 Reales/Libra = S$ 40. at Paris, trade?
At the Spanish Onza (0.9243 Ozt), 20 Reales = S$ 2.50 x 1,600 Onza = S$ 40,000.
∴ 320,000 Reales = L.T. 153,300, so 1 Paris Marc cost L.T. 81.4035; S$ 21.28
If 20 Livres/Once, = 320 L.T./Livre p.d.m or 160 L.T./Marc. = S$ 38.10/Livre;
S$ 19.05/Marc.
The wholesale price of Crown platina ore was debated, unchanged. For the Spanish Crown this base-cost does not appear to include transport, salaries, etc. therefore it must be an absolute European low price for ore, rather than anything approaching a market-price.
?-1794: 1 Troy Ounce platina (Spanish Crown) = S$ 0.1352 (L.T. 0.5206)
1795: 1 Troy Oz. platina (Chocó Spot) = S$ 0.541 (L.T. 2.069)
1795/6 : 1 Troy Oz. platina (Paris Market) = S$ 1.48 (L.T. 10.345)

The most important executed request was by France in late 1795, in which the charge d'affaires of the French Republic solicited 10 arrobas of platina for the Committee of Public Instruction, a request possibly related to the manufacture of the new weights standards being manufactured in Paris at that time by Marc Étienne Janety (1739 - 1820), for already in November of that year he began working with 200 marcs {1,573.8 Ozt} of platina [59]. No objections were made to the request to graciously give platina, by asking of the Hacienda about what importance is 10 Arrobas {14,790 Ozt}, according to estimates they believed this Metal has [60]. The response indicates that platina has been purchased 4 Reales per Onza {S$ 0.541} so that the total 16,000 Reals {P$ 500. @ L.T. 15.4 = L.T. 7,700 for 10 Arrobas} should not be charged thus, as has been done in the past.
La petición más importante es la llevada a cabo por Francia hacia finales de 1795{"3"?} en la que el encargado de negocios de la Repŭblica Francesa solicita 10 arrobas de platina bruta para la Junta de Instrucción Pŭblica, petición posiblemente relacionada con la fabricación de los nuevos pesos patrón que por esa fecha se están fabricando en París por Marc Étienne Janety (1739- 1820), quien ya en noviembre de ese año empieza a trabajar con 200 marcos de platina bruta [59]. No se ponen reparos a la solicitud, aunque sí a ceder graciosamente la platina, pidiéndose a Hacienda información acerca de quanto importan las 10 Arrobas, segŭn la estima que se cree tiene este Metal [60]. En la respuesta se señala que se ha pagado la platina a 4 reales la onza, por lo que el total importa 16.000 reales y que no debe cobrarse, al igual que se ha hecho en otras ocasiones.
1795/6 : 1 Troy Oz. platina (Spanish Market, retail?) = S$ 1.48 (L.T. 10.345)
Not convinced by this resolution seems to be Madrid lapidary Pedro Puch, who said that the price of platina is "20 Reals/Onza" {December 1796} and for that it should be resolved Chabaneau deliver the platina to the French charge d'affaires on payment of the amount [62]; however the consul received and paid for the expressed amount untreated, according to Pierre-Francois Chabaneau [63]. Later Godoy informed the Treasury that the King has seen fit not to charge the platina to Paris. [64] Nicolas Butrow, charge d'affaires at the Russian court, asks a few libras of platina in 1798 for a minister, whose name is not stated...
No debe convencer esta resolución y se pide parecer al lapidario madrileño Pedro Puch quien declara que el precio de la platina es de "20 reales/onza" por lo que se resuelve que Chabaneau entregue la platina al encargado de negocios francés previo abono del importe [62]; sin embargo el cánsul recibió la expresada cantidad sin tratar de su pago, segŭn acaba de participar D. n Fran. c° Chavaneau [63]. Tiempo después Godoy comunica a la Secretaría de Hacienda que el rey ha tenido a bien no cobrar la platina a París [64]. Nicolas Butrow, encargado de negocios de la corte de Rusia, pide en 1798 algunas libras de platina para un ministro, cuyo nombre no se señala, de la
