This Belgian text cites Restrepo (1884) but gives a dramatically lower platina price. This might be a typographical error, or a local spot-price for ore.

1884: 1 Troy Oz. platina (Source: Choco, Colombia; 85% ore) = Fr 9.33 (USD$ )

1884: 1 Troy Oz. platina (Source: Colombia; 85% ore) = Fr 10.97 (USD$ )
