Colombia, 1805-09: Platina Export Price

DSQ



Visiting Chocó in 1801, Alexander vonHumboldt subsequently declared the spot-price for platina was 8 Piastres Reals per Spanish Pound (= 100 castellanos [1 castellano = 71 grains troy] = 7100 grains = 14.792 troy ounces.)  Whereas von Humboldt's specimen-price might have been the higher local rate for very best quality ore (and a poor trade), the market-price for bulk or wholesale platina was certainly much lower. 

Given a presumed exchange at Cartagena for Sterling (S$ 1. = £0.2082) and an 8% premium for 'Spanish Plate' in the former English Colonies (USA: 6 Piastres = [1.08*$6.], etc.) the trader's export rates for Colombian platina may be estimated

1 Troy Ounce platina (raw ore, in Colombia) = S$ 0.541
1 Troy Ounce platina (raw ore, in Colombia) = USD$ 0.584

1 Troy Ounce platina (raw ore, in Colombia) = Fr 1.01

1805: 1 Troy Ounce platina (Cartagena) ~ S$ 0.406 
1806: 1 Troy Ounce platina (Cartagena) ~ S$ 0.406  
1807: 1 Troy Ounce platina (Cartagena) ~ S$ 0.406 

1808: 1 Troy Ounce platina (Cartagena) ~ S$ 0.406 
1809: 1 Troy Ounce platina (Cartagena) ~ S$ 0.406  

Mollien's confusion must include the total volume of platina exported: 6,000 libras is 2,760 kgs, an impossibly high annual export.  At 6,000 castellanos (60 libras), the yearly recorded platina export was more likely 888 ozt. (27.6 kgs.)  Had the estimated value been 6 reales per castellano (S$ 0.75) or S$ 75. per libra, the European price would have been multiples higher - also impossible.

At English Retail, 1 Libra platina sold in the UK cost S$ 17.59 - 17.85; the European Commercial Price was ~3x greater than at export.

Reconciliation implying an official annual export of 60 libras @ S$ 6. per, ~S$ 360. with an unknown additional export (5x greater?) as contraband, perhaps ~ 165.6 kgs/ann. in a poor period of precious metals production?

Where the specific gravity of Platinum was assumed 21.3, Wollaston's platina was between ~70.4% - 79.81% pure.

From 1804 - 09, Carthagena was essentially a free-trade open-port.  In this time, Chocó slaves could profitably extract for masters but also illicitly gather and sell the metal, purchasing their own or loved ones' freedom.  By Mollien's erroneous estimation ('correction'?) above, the annual platina export from 1804-09 was 88,752 Troy Ounces (2,760.6 kilgrams).  Resprepo's (1809) estimate was 81,356 English Troy Ounces (2,530 kgs or 1,240.9 libras) or ~248 kgs annually.

In 1804, the Barca El Serrano carried 134.54 kgs to Cadiz and the British Navy intercepted another ~124.4 kgs.  This suggests a minimum official platina export to Europe ~719 kgs that year alone.

With increasing manumission during the Civil Wars and after trade restrictions were imposed, the platina yield likewise fell after 1818. According to Cochrane, visiting in 1823 when Colombian Platinum was in greatest demand, about ten quintales of platina (14,790 English Troy Ounces, or 460 kgs) were extracted annually from Chocó.  Dr. Jose Manuel Restrepo reported at the price peak (1826) : "the amount of platinum that is exported is small, which sound data indicates cannot exceed 1,500 libras ( = 22,188 Troy Ounces or 690.14 Kgs) per year.  Platinum is worth 16 to 20 pesos per libra."

Resrepo (1809) estimated Gold yield at 2,300 - 2,760 kgs per year; therefore, platina was 25-30% that amount or about one-fifth the total PM yield for the region.

In 1809 Dr. José Manuel Restrepo, published an essay on the geography of Antioquia in the weekly El Semanario de la Nueva Granada:  "[In 1808 ] this branch of industry, the only export, amounted annually 500 - 600,000 castellanos (1,250,000 pesos), according to the best estimates."

The Colombian source price was steadily declining, 1803-14. This corresponds to both the falling London Platina price (recorded by Wollaston) and the Paris Platinum Collapse in 1811/2.

In late 1801/ early 1802, the Spanish Crown attempted to reassert control over the illicit trade in platina contraband ; by May 1803, however, British merchants had free reign on the Spanish Main. It appears likewise from Wollaston's account books: the source price of platina was falling almost continuously for a decade.

Spanish merchants typically marked-up imported contraband goods for retail 25-35%; it's not clear commodities from the interior rose as much.


Mollien (1824) cites a Consulate official's estimation to the Viceroy of the average price-weight Choco platina "during the six years anterior to 1810" @ 6 Piastres per Spanish Pound at Carthagena.  (The French traveler's 1823 Choco platina spot-price is far too low, by a local German merchant's opinion.)

The Colombia export price of platina was dropping fast. The price bottom was presumably reached in 1811/12, when Cuoq, Couturier & Cie. acquired a very large supply and caused the price of refined Platinum in Paris to drop by >50% in Paris, c.1815.

The Wuretmburg Centner corresponded to the Spanish quintal almost exactly, 103 lbs avoirdupois.


The very stable London retail prices seem indicative. Despite rising demand, Wollaston's suppliers' prices trended down for nearly 15 years. Sharply falling Paris retail prices in the same period are also evident. All these factors imply declining wholesale platina prices, despite any brief interruptions in trade (due to war):

Where the Antioquia Gold Yield of 1808/9 was 550,000 castellanos (2,531.8 Kgs, 81,400 Ozt.), the Platinum Yield should be ~305,555 castellanos (1,406.6 Kgs, 45,222 Ozt.)

c.1809: The Santo Domingo platina export was weak, and the quality inferior. But mention of the low price may either reflect both a general depression in the global ore price or the effect of a 'new source' for the metal (which may simply have been smuggled there.)

These sands, which also contain some gold, are picked by women, who, without treating them like the miners, sell them for a few maravedis.

As this strange apprehension was not valid, and because of the size and utility of Platinum instruments which appeared in France, the banning of exports of platinum in America was no longer observed and died in 1808. There were namely boilers, pistons and the like for factory use.  But even in this period (c.1800-1822) the use of platinum remained very limited, because the whole annual yield of crude platinum from Brazil, Colombia, and later Haiti, was not more than 25 poods (8.5 Center = 437.6 kgs = 14,069 ozt)


c. 1805-09:

At full weight, the Carlos IV ("IIII") 8-Escudos was 27.07 g, .875 fine gold, 36.40 mm diameter. A circulated 8-Escudos might weight ~ 26.85 g. 


This 1804 contemporary 8-Escudos counterfeit (Popayan mintmark. JF assayer: Fr-52; KM-62.2) in Platinum was about Uncirculated: 36.5 mm. 1.5 mm thick. 26.68 g.

The Surface Area of this particular Platinum Counterfeit (+0.05, in relief) was ~22.7 cm²

 At full weight, this coin would presumably have at least an additional 0.443 g Gold surface, ~6.8 Grains Troy.

Perhaps significant at certain points, the value of Spanish Dollars (and bullion generally) rose dramatically in some months, a factor inflating/distorting commodity prices from the Spanish Main, certainly.
