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 bullion price impossible. One and the same piece of metal can even fulfill both purposes simultaneously, as will be seen if we think of ornaments that are used as money or of a coin that is worn by its owner as jewelry until he parts with it again.15
Investigations into the foundations of the value of money must eliminate those determinants that arise from the properties of the monetary material as a commodity, since these present no peculiarity that could distinguish the value of money from that of other commodities. The value of commodity money is of importance for monetary theory only insofar as it depends on the peculiar economic position of the money, on its function as a common medium of exchange. Changes in the value of the monetary material that arise from its characteristics as a commodity are consequently to be considered only so far as they seem likely to make it more or less suitable for performing the function of money. Apart from this, monetary theory must take the value of the monetary material that arises from its industrial usefulness as given.
The material of which commodity money is made must have the same value whether it is used as money or otherwise. Whether a change in the value of gold originates in its employment as money or in its employment as a commodity, in either case the value of the whole stock changes uniformly.16
It is otherwise with credit money and fiat money. With these, the substance that bears the impression is essentially insignificant in the determination of the value of the money. In some circumstances it may have a relatively high exchange value comprising a considerable fraction of the total exchange value of the individual coin or note. But this value, which is not based on the monetary properties of the coin or note, only becomes of practical importance at the moment when the value based on the monetary property vanishes, that is, at the moment when the individuals participating in commerce cease to use the coin or note in question as a common medium of exchange. When this is not the case, the coins or notes bearing the monetary impression must have a higher exchange value than other pieces of the same material so long as these are not marked out by any special characteristics.
Again, in the case of credit money the claims used as money have similarly a different exchange value from other claims of the same kind that are not used as money. The hundred-gulden notes which circulated as money in Austria-Hungary before the reform of the currency had a higher exchange value than, say, a government security with a nominal value of a hundred gulden, notwithstanding the fact that the latter bore interest and the former did not.
Until gold was used as money it was valued merely on account of the possibility of using it for ornamental purposes. If it had never been used as money, or if it had ceased to be so used, its present-day value would be determined solely by the extent to which it was known to be useful in industry. But additional opportunities of using it provided an addition to the original reasons for esteeming it; gold began to be valued partly because it could be used as a common medium of exchange. It is not surprising that its value consequently rose, or that at least a decrease in its value which possibly would have occurred for other reasons was counterbalanced. Nowadays the value of gold, our principal modern monetary material, is based on both possibilities of employment, on that for monetary purposes and on that for industrial purposes.17
It is impossible to say how far the present value of money depends on its monetary employment and how far on its industrial employment. When the institution of money was first established, the industrial basis of the value of the precious metals may have preponderated; but with progress in the monetary organization of economic life the monetary employment has become more and more important. It is certain that nowadays the value of gold is largely supported by its monetary employment, and that its demonetization would affect its price in an overwhelming fashion.18 The sharp decline in the price of silver since 1873 is recognized as largely due to the demonetization of this metal in most countries. And when, between 1914 and 1918, many countries replaced gold by banknotes and Treasury notes so that gold flowed to those countries that had remained on a gold standard, the value of gold fell very considerably.
The value of the materials that are used for the manufacture of fiat money and credit money is also influenced by their use as money as well as by all their other uses. The production of token coins is nowadays one of the most important uses of silver, for example. Again, when the minting of coins from nickel was begun over fifty years ago, the price of nickel rose so sharply that the director of the English mint stated in 1873 that if minting from nickel were continued the cost of the metal alone would exceed the face value of the coins.19 If we prefer to regard this sort of use as industrial and not monetary, however, it is because token coins are not money but money substitutes, and consequently the peculiar interactions between changes in the value of money and changes in the value of the monetary material are absent in these cases.
The task of the theory of the value of money is to expound the laws which regulate the determination of the objective exchange value of money. It is not its business to concern itself with the determination of the value of the material from which commodity money is made so far as this value does not depend on the monetary, but on the other, employment of this material. Neither is it its task to concern itself with the determination of the value of those materials that are used for making the concrete embodiments of fiat money. It discusses the objective exchange value of money only insofar as this depends on its monetary function.
The other forms of value present no special problems for the theory of the value of money. There is nothing to be said about the subjective value of money that differs in any way from what economics teaches of the subjective value of other economic goods. And all that it is important to know about the objective use-value of money may be summed up in the one statement—it depends on the objective exchange value of money.

1 The Dependence of the Subjective Valuation of Money on the Existence of Objective Exchange Value
According to modern value theory, price is the resultant of the interaction in the market of subjective valuations of commodities and price goods. From beginning to end, it is the product of subjective valuations. Goods are valued by the individuals exchanging them, according to their subjective use-values, and their exchange ratios are determined within that range where both supply and demand are in exact quantitative equilibrium. The law of price stated by Menger and Böhm-Bawerk provides a complete and numerically precise explanation of these exchange ratios; it accounts exhaustively for all the phenomena of direct exchange. In bilateral competition, the market price is determined within an area bounded on the top by the valuations of the last successful buyer and of the most
