Colombia, 1832

A Colombian argued against the current and long-standing 'state monopoly asset price' for something closer to the local black market Bulk Spot-Price. (We can infer the largest platina producers were foward-selling at this rate.) 

The actual Black Market Export Price is unstated here, but probably 50-100% over the set rate.

Sept, 1832: 1 Troy Ounce platina (@ Choco, Specific Gravity 22)  = C$ 0.5409

"Mi parecer es, que se deje libre la esportacion de la platina á los mismos mineros:que se ponga el precio de ocho pesos á cada libra: que se prohiba á los particulares la sompra de ella, i se verà abundar este metal, porque entónces los mineros tendrán utilidad en lavarla i escejarla, como hacen con el oro."

"My opinion is let the export of the platina by the same miners  be free; that the price  be fixed per Libra at eight pesos; that private business in its trade be forbidden to individuals, and this metal will be abundant, because then the miners will have utility in washing it and cleaning it, as they do with gold.

Colombia, 1846

An October 1846 storm hit Havana, sank a Liverpool vessel with 1,372 ounces of platina.

The actual 'value' of Platinum should be either 'Market, Unmfg.' or 'Scrap, Retail Bid'; this 1878 estimate was correct.

The New York exchange rate (Sight) at the end of January 1919 was USD $1. = Fr. 5.4625 

It appears the Paris Market for Platinum was 30.65% higher than the US Gov't price for ingot. That is consistent with a recent numismatic premium for US Gold coin in NYC.

September 1878: 1  Ozt. Platinum (Paris: Mkt) = Fr 37.32  (USD$ 7.23)
 
1878: 1 Troy Oz. Gold = Fr.106.90   (USD$ )
1878: 1 Ozt. Platinum = Fr. 35.60  (USD$ )

1/20/1919: 1  Ozt. Platinum = Fr. 641.40 - 748.30 (USD$ 117.42 - 137.)
January 1919: 1 Ozt. Platinum (Ingot @ US Govt) = USD$ 104.85

"Monnaies de platine (LXXVII; LXXVIII). - En 1877 a Cherchel et l'année suivante à Orléansville il y avait en circulation des pièces de 20 frs. en platine doré a l'effigie de Napoléon III. Les premières portaient la marque de Paris (1860); les secondes étaient au coin de l'Hôtel des monnaies de Strasbourg (1866). Le journal de pharmacie et de chimie d'avril 1878 a publié une note à ce sujet. La valeur du platine n'était alors que le tiers de celle du l'or. Elle est, aujourd'hui, 6 ou 7 fois plus élevée.      B. A."
