sovereign in circulation, so that the ratio fixed for
the rupee was not with a domestic coin but with one
circulating in another country, and could therefore
only be seen at work in the business transactions
between the two countries, commonly called the
axchanges. Hence the name “ gold-exchange stan-
dard ” applied to the monetary system of India
and other countries with silver currencies kept to the
standard of gold. But we must beware of imagining
any natural pre-eminence of gold over silver. The
same system might be applied with equal ease to
keeping the value of a gold coin at some fixed ratio
with the value of the silver coin of another country
or indeed with the value of any other clearly cognizable
commodity or even with a collection of commodities
such as appears in the formation of an index number
of prices. The Swedish Government came near
adopting a plan of this kind in 1916, when it put
hindrances in the way of the entry of new gold, but
the object to be aimed at was not properly understood,
and the manufacture of paper substitutes for coin
was not adequately limited, so that the experiment
proved completely abortive, the value of the Swedish
currency eventually falling not only down to but
considerably below its original parity with gold.

after 1914, pp. 79-100.)
The conclusion of this section is that given demand
for a coin, adequate restriction of supply will keep
its value up to any required level above that of its
metallic contents. It is not, of course, a useful
corollary of this to say that adequate additions to
supply would keep its value down to any required
level below that of its metallic contents: that is
perfectly true, but adequate additions cannot be
made, because a coin worth less as a coin than the
bullion of which it is made will always, law or no law,
