"On the Economy of Machinery and Manufactures"

But when a piece of platinum is cut into two parts, it
cannot easily be reunited except by means of a chemical process,
in which both parts are dissolved in an acid. Hence, when
platinum coin is too abundant, it cannot, like gold, be reduced
into masses by melting, but must pass through an expensive
process to render it useful.

Chapter 15
On the Influence of Verification on Price
181. The money price of an article at any given period is
usually stated to depend upon the proportion between the supply
and the demand. The average price of the same article during a
long period, is said to depend, ultimately, on the power of
producing and selling it with the ordinary profits of capital.
But these principles, although true in their general sense, are
yet so often modified by the influence of others, that it becomes
necessary to examine a little into the disturbing forces.
182. With respect to the first of these propositions, it may
be observed, that the cost of any article to the purchaser
includes, besides the ratio of the supply to the demand, another
element, which, though often of little importance, is, in many
cases, of great consequence.
