Until the 1830s, Palladium was exceeding rare and nominally cost about 10x the POG. As such, it was not widely employed by any industry.
When O.N. Johnson (of Johnson & Matthey) began refining of a fairly large supply of palladium-gold from mines in Brazil (1834-40), the Palladium price collapsed.
Given the sudden oversupply, the London price fell continuously from 1834 - c.1844. Dentists and fine metalworkers soon employed Palladium at a less than one-quarter the POG, and demand increased with industrial innovations of the day.
By 1835, the price had fallen by about 2/3rds:
1834/5: 1 Troy Ounce Palladium (refined) = £ 2.20 (USD$ 10.67)
