Platinum pens sold for Fr 6. (S$ 1.14) in mid-1812:





In 1811/2, Cuoq, Courturier & Cie. imported a large quantity of platina and founded a factory with M. Bréant (employing Wollaston's refining process) to mass-produce platinum wares.  That Platinum came to market after 1813, a lag-time that was half the duration of the Wollaston effort (1800>1805.)

The French joint venture so successfully cornered the platina market that Wollaston was himself was driven out of the business by 1820. In France, this period of oversupply (1814-22) technically lasted until 1825, although other factors began elevating the French price-level c.1826.

Platinum was confirmed in Brazil c. 1809, reported c. 1811 and well-known by 1812.  That discovery may have greatly diminished any speculative pressure, and encouraged Colombian hoarders to begin dumping platina.
