UK, 1868: Alfred Apps Catalogue (London, n.d.)

Assuming 1907 Gold Standard forex (£ 1. = ℳ 20.42105) and presumably excluding transport, Customs, etc.

1868: 1 Troy Oz. platina (Ural Spot: Ore, Bulk) = £ 0.3183 ($ 1.55)
1868: 1 Ozt. platina (Ural Spot: Ore @ 999, Bulk) = £ 0.4244 ($ 2.06)

Matthey paid per kilogram 1868 .... ℳ 209, 1877 .... ℳ 313.5, 1880 .... ℳ 390.5, 
(Prices are based on the spot crude platina, and are average prices. Prices for pure Platinum are of course correspondingly higher.)

Citation: Prometheus: Illustrierte Wochenschrift über die Fortschritte..., Vol. 18, No. 904, p.309


The first general catalogue may be from 1868. The App Inductorium was exhibited in 1868; the Grove Batteries are sold in the second brochure as an essential accessory.

In the main catalogue, the Grove Battery with 5"x2.25" Platinum cost £ 0.575.


c.1868?: 1 Troy Oz. Platinum (Semi-Mfg, Trade: Sheet) = £ 1.50

Citation: Catalogue of Optical, Mathematical & Philosophical Instruments Manufactured by APPS,433,WEST STRAND, LONDON, W.C. (Nearly opposite Charing Cross Railway Station.)" G. Shield Printer 30 Sloane St. Chelsea (n.d. 1867?) 16pp. p 9,10





In second brochure, some years later, the (half-pint) Grove Battery of 4"x2" Platinum sheet cost £ 0.55 ; 5"x2.25" cost £ 0.575 - 0.5833 per; as low as £ 0.55 for a great number.

Citation: (same item; second brochure)


c.1868: Capsule prices were slightly higher than in 1871.


Citation: Exercises in practical chemistry ... Augustus George Vernon-Harcourt, Henry George Madan (1869) p.17



Most "commercial Palladium Wire" was not pure but 40-60% silver. 

1868: 1 Troy Ounce PALLADIUM (pure, retail)  = £ 8. (USD$ 54.64)
 
Citation: The Student, and intellectual observer, Volume 3 (1869), p.150.



A complete set of mineral teeth (14x2= 28, manufactured) cost £ 2. to the trade, £ 3. - 3.50 retail. Markup, 33-75%. Where 28 mineral teeth retail (unmanufactured) cost £ 4.90, £ 7. (Ag),  £ 10.50 (Pt), £ 14. (18k = .750 Fine Au) by extrapolation, the retail price for a complete Set of mineral teeth on Vulcanite:


in Silver: wholesale £ 3.40 - 3.50 ; retail £ 4.60 - 5.0
in Platinum wholesale £ 4.50 ; retail £ 6.50 - 7.50
in Gold wholesale £ 4.50 ; retail £ 8.50 - 10.


1867: 1 Troy Oz. Gold (Trade: 20k Dental) = £ 4.11 ($ 20. Gold)

1867: 1 Troy Oz. Platinum (Trade: 20k Dental) = £ 3.08 ($ 15. Gold)

April - August 1868:

A complete set of mineral teeth on vulcanite, £ 5., on Platinized Silver £ 6., on Platinum
£ 9. on Gold £ 12.  Platinum dentures of approximately the same weight cost 75% the price of Gold. Labor additional.


Where the intrinsic value of Gold was £ 2.50, Scrap @ £ 4.248/Ozt Fine Au, the highest weight of Fine Gold in Scrap was 0.494 Ozt, or 0.593 Ozt in 20k Alloy.  Factoring different specific gravities and the maximum 35% heavier plate, we might estimate a 0.80 Ozt in Platinum Plate (dentures weighing ~2.5 Ozt)

All workmanship/labor held the same, the addition of Gold (~0.5 Ozt) raised the cost £ 7. - 10. over vulcanite; assumed to be 0.80 Ozt, Platinum Plate likewise raised the cost £ 4.  over vulcanite.  Adjusting for the weight differential in precious metals, Platinum was about one-third the retail Price of Gold.

1868: 1 Troy Oz. Gold (Retail: 20k Dental) = £ 14. - £ 20.
1868: 1 Troy Oz. Platinum (Retail: .999 Dental) = £ 5.
 





Adjusting for Real Inflation since 1869 (4,648%) we can extrapolate a long term retail price for refined & manufactured pure Palladium to be $ 4,083. -  6,172. (in 2009 USD$.)
