The Theory of Money and Credit - Ludwig von Mises [51]
The case of money is different. Its objective exchange value cannot be referred back to any sort of use-value independent of the existence of this objective exchange value. In the origins of monetary systems, money is still a commodity which eventually ceases to circulate on reaching the hands of a final buyer or consumer. [12] In the early stages of the history of money there were even monetary commodities whose natural qualities definitely precluded their employment as money for more than a short time. An ox or a sack of corn cannot remain in circulation for ever; it has sooner or later to be withdrawn for consumption if that part of its value which does not depend on its employment as money is not to be diminished by a deterioration of its substance. In a developed monetary system, on the other hand, we find commodity money, of which large quantifies remain constantly in circulation and are never consumed or used in industry; credit money, whose foundation, the claim to payment, is never made use of; and possibly even fiat money, which has no use at all except as money.
Many of the most eminent economists have taken it for granted that the value of money and of the material of which it is made depends solely on its industrial employment and that the purchasing power of our present-day metallic money, for instance, and consequently the possibility of its continued employment as money, would immediately disappear if the properties of the monetary material as a useful metal were done away with by some accident or other. [13] Nowadays this opinion is no longer tenable, not merely because there is a whole series of phenomena which it leaves unaccounted for, but chiefly because it is in any case opposed to the fundamental laws of the theory of economic value. To assert that the value of money is based on the nonmonetary employment of its material is to eliminate the real problem altogether. [14] Not only have we to explain the possibility of fiat money, the material of which has a far lower value without the official stamp than with it; we must also answer the question, whether the possibility of a monetary employment of the commodity money material affects its utility and consequently its value, and if so to what extent. The same problem arises in the case of credit money.
Part of the stock of gold at the command of mankind is used for monetary purposes, part for industrial. A change from one kind of use to the other is always possible. Ingots pass from the vaults of the banks to the workshops of the goldsmiths and gilders, who also directly withdraw current coins from circulation and melt them down. On the other hand, things made of gold, even with a high value as works of art, find their way to the mint when unfavorable market conditions render a sale at anything higher than the
