In February 1801, Richard Knight sold 800 Troy Ounces of platina to Messrs. Wollaston & Tennant for 4s./ozt., nearly double the average bulk-rate
The London Price appears to more than double the estimated Cartagena wholesale price (S$7./libra.) This was more than 25% higher than Wollaston's average price paid.
1801: 1 Troy Ounce platina (Knight's resale, mkt?) = £ 0.20 (S$ 1.2225)
October, 1801: 1 Troy Oz. platina (specimen rate @ Choco) = S$ 0.5408 (£ 0.1217)
1801: 1 Troy Oz. platina (Cartagena Mkt) ~ S$ 0.4731 (£ 0.0774)

Russia: 1798
c.1798/9: Count de Mussin Puschkine offered to reveal his method of amalgamating platinum sponge for 150 Фунт ( =61.43 kgs., or 1,974.93 Troy Oz.) a request likely directed to the Russian or Spanish Crown rather than any contraband trader. (He disclosed an already known method using mercury in 1800.) What was the 1798 St. Petersburg cost in Silver Roubles for 1,975 Troy Oz. Spanish platina?
In 1793, the French government paid L.T. 2,716.50 for 1,781.35 Ozt, equivalent to L.T. 3,011.71 (1798: руб 803.11) for 150 Фунт, or L.T. 20.08/Фунт.
In 1795, the French government was charged L.T. 7,700 for 14,790 Oz, equivalent to L.T. 1,028.22 (1798: руб 274.19) for 150 Фунт, or L.T. 6.85/Фунт.
In 1795, at the Market-Price S$ 8./Libra, 1,975 Ozt cost L.T. 4,086.4 (1798: руб 1,089.71), or L.T. 27.24/Фунт.
At L.T. 1 = руб 0.267, if 150 Фунт (1,975 Ozt) cost ~ L.T. 24/Фунт, (1798: руб 6.40/Фунт)
was likely 960 руб Ag, ~ 1,315 руб Acc.
If correct, Count de Mussin Puschkine valuation for 150 Фунт was ~1,000 руб.

At purity, 1,975 Ozt of 70% ore reduces to 1,382.45 Ozt. (This does not factor any labor, manufacture/trade fees.)

Reported Wien, March 1800:
Mussin-Puschkin's offer was reported in English journals, July 1800:
In 1804, Count Mussin-Puschkin inserted himself into the Chevenix-Wollaston Palladium Controversy. Unless he was lying outright - a distinct possibility - he mentions a large platina purchase, (in 1802) by British mineral dealer for the Russian State (in St. Petersburg) and then on two subsequent occasions, bulk sales by the Count (back to?) said dealer.
Let alone the effort of teaching someone the platinum working skills, the time required to process the platina and convey the Palladium thence to a relation in London is abit absurd.
Mussin-Puschkin's claim of having held large amounts of Platinum c.1802 is of interest, at any rate. There was a platina demand in St. Petersburg, and trade in the Colombian ore.

"a recent sale at Christie's (23 July 1965 or 1 March, 1966) , when Lord Margadale sold the coins and medals collected by his grandfather, Alfred Morrison, there is no less interest in commemorative medals of the past. Fig.3 for instance, a platinum medal dated the year 6 of the Revolution showing Napoleon as General-in-Chief of the army in Italy and commemorating the peace in that year, made £.650. {USD$ 233. - 231.73} The artist is Duvivier. The reverse, the mounted conqueror crowned with a laurel wreath by, I presume, Victory, is no doubt banal enough in its severe neo-classic manner; it is interesting though, that, according to the inscription, it is not the nation which is expressing its thanks, but "Les Sciences et Les Arts Reconnaissants..."

Italy, 1916
From 1912 - 1916, the inflation rate of London 'official Platinum Price' was 52.63%. The New York Platinum Price rose 97.5%. Ettore Mollinari (or the translator of the 1919 4th Edition) suggests the actual Italian Platinum Price inflation-rate was 232.4% .
In 1912, the Lire/Sterling exchange was ₤ 23.83 : £ 1. (₤ 1. : £ 0.03871) and January 1917, the Lire/Sterling exchange was ₤ 32.78 : £ 1. (₤ 1. : £ 0.03051), so the Lire inflation rate of London Platinum should have been ~ 93.7%.
