Adam Hilger, a British manufacturer of spectroscopes: " "Iridium-platinum," he writes in March 1879, " is a very fine metal, but rather very dear.

A piece I bought the other day, {1/8th?} inch thick by 1.5 inch square, rather full in size, came to £13. I almost fainted at such an awful price : still it was ordered, and I had to pay for it.

January, 1879:
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.
Platinum teeth were advertised 25% cheaper than 1867.
Later on, dental alloys usually contained little Gold or Platinum, yet still matched (or slightly discounted) the Platinum price. In this way, dentists were accustomed to substituting Platinum or Palladium for Gold in their industrial purposes. Psychologically, this may have supported this particular industrial Price/Demand.
