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$.)
