1865: 1 Ozt. Platinum (Frankfurt: Wire, Ret.) = $ 5.822 (Fl 14.308)
1865: 1865: 1 Ozt. Platinum (Paris: Mfg, Bulk) = $ 6.35 ; USD$ 10. (Fr 32.66)
1865: 1 Ozt. Platinum (Paris: Mfg, Bulk) = $ 6.48 ; USD$ 10.20 (Fr 33.33)
Late 1865: 1 Ozt. Platinum (London: Ret.? Mkt) = $ 7.31 (£ 1.50)
From a telegraphic student's manual; 1 dwt. (pennyweight) = 1/20th Troy Ounce. Catalogues in 1852, 1853 show Platinum Plate & Wire sold at the same rate.
It would appear the USD price is basically double the Producer's wholesale rate.
