In 1877-8, Mexico (re-)exported 24.09 Kilograms = 774.51 Ozt. platina ore for M$ 2,505.88: per Kilogram (32.15 Ozt) M$ 104. (C$ 95.68)

Colombia, 1878

Robert Blake White was resident 17 years in Colombia ; he voyaged up the River Atrato in 1878.  As reported to the Royal Geographical Society five years later, the local quote for Colombian platina was nearly half the London market price for imported ore.  (The actual bulk price paid to small local producers, in trade goods, was likely about half the Source Spot; merchant trade set the market, not specie.)

Where the Colombian peso = 4s. but export transaction were estimated in Fr. 5 (Ag coin units), platina ore @82.5% from Chocó cost a maximum:

Per Libra (14.792 Ozt.) ~ C$ 44.50 (£ 8.75; Fr. 222.50; USD$ 42.95), or 
Per Kilogram (32.15 Ozt) C$ 96.5 (£ 19.; Fr. 482.50; USD$ 93.)

1878: 1 Troy Oz. platina (Nóvita Spot: 82.5% Ore) = C$ 3.  
(Fr. 15., ~£ 0.60 ; USD$ 2.90)

1878: 1 Troy Oz. Pt (Nóvita Spot: .999 Ore) = C$ 3.64 

(Fr. 18.18, ~£ 0.73 ; USD$ 3.52)

1878: 1 Troy Oz. platina (Colombian .999, w/postage) ~ C.$ 4.311 (USD$ 3.601)

The Mexican re-export rate was 44% higher than the Colombian Source-Price.
 

1878: 1 Troy Oz. platina (Mexico: ore, re-export) = $ 3.24

1878: 1 Troy Oz. platina (Rus ore: London, bulk) ~ £ 0.96 (USD$ 5.)

The Colombian platina purity was rated 89%



Postage: Apparently, postage to NYC was (C$ 0.34 + 0.60)  ~C$ 0.94 per Ounce.

USA, 1872: Palladium

Apparently without qualification, contemporaries mention 'English prices' for Palladium without accounting for shipping costs.   The US wholesale price for Pd was approximately 100% higher; in the USA, pure Palladium retailed nearly 10x more expensive than Platinum at this time.

The total Unit Cost of a single Grove's Cell w/ one 6" x 2" foil (24" sq. surface) is £ 0.23, where a single foil cost £ 0.14 (@ £ 0.01125 per sq.in.) or 59% of the Unit Cost. At a known Platinum price per oz. troy, there might have been 11-12 6"x 2" platinum foils per ounce troy. Presumably, these are 'smaller' foils (by the sheer number used) - or the Platinum price estimation is off by 50%.

At a known Platinum price per oz. troy. There were 6 6"x 3" foils (£ 0.23 each) or 8 platinum foils per ounce troy. Presumably, these are medium-sized foils.

In Grove's Cell, there were four to six (larger) platinum foils per troy ounce by this estimation.
