Citation: Le Moniteur scientifique du Doctor Quesneville: Journal ..., Vol. 39-40 G. A. Quesneville, p.664



1870: 1 Troy Ounce Pt (Still Labor) = Fr 13.56 (USD$ 2.65)

1870: 1 Troy Ounce Pt (Still Labor) = Fr 39.53 (USD$ 7.73)
1870: 1 Troy Oz. Pt (Still Labor) = Fr 42.88 (USD$ 8.39)

 The rate at which the old Platinum was taken is unclear, but critical. Assuming the same scrap rate from the same dealer (in 1870 and 1873) might be useful.

'Repair cost' is assumed to be Labor (unknown) + new Platinum (201.75 Troy Oz.) + scrap Pt allowance (unknown value for 51.96 Troy Oz.)

Given the total scrap value in 1873, an estimation of the 1870 scrap rate is fair: 

1870: 1 Troy Oz. Platinum (scrap, bought) ~ Fr  17.11 ($ 3.35)
1873: 1 Troy Oz. Platinum (scrap, bought) = Fr 25.15 ($ 4.83; USD$ 5.58)
