Commodities enter the process of exchange in the concrete form of use-values. They are yet to be turned into the real universal equivalent through their alienation. The determination of their prices merely amounts to their ideal transformation into the universal equivalent, a process of equation to gold which is yet to be realized. But since commodities are, in their prices, transformed into gold only in imagination, or are converted only into imaginary gold, and since their money form is not differentiated as yet from their concrete selves, it follows that gold has also been turned into money only in imagination; it appears so far but as a measure of value, and in fact definite quantities of gold serve merely as names for certain quantities of labor-time. The form in which gold is crystallized in money Pg 80always depends upon the way in which commodities express their own exchange value to each other.
Commodities now confront one another in a double capacity: actually as use-values, ideally as exchange values. The twofold aspect of labor contained in them is reflected in their mutual relations; the special concrete labor being virtually present as their use-value, while universal abstract labor-time is ideally represented in their price in which commodities appear as commensurable embodiments of the same value—substance differing merely in quantity.
The difference between exchange value and price appears to be merely nominal or, as Adam Smith says, labor is the real price, and money the nominal price of commodities. Instead of estimating the value of one quarter of wheat in thirty days of labor, it is estimated in one ounce of gold if one ounce of gold is the product of thirty days 'labor. However, far from this difference being merely nominal, all the storms which threaten commodities in the actual process of circulation center about it. Thirty days of labor are contained in a quarter Pg 81of wheat and it need not, therefore, be expressed in terms of labor-time. But gold is a commodity distinct from wheat, and only in circulation it can be ascertained, whether the quarter of wheat can be actually turned into an ounce of gold as is anticipated in its price. That will depend on whether or not it proves to be a use-value, whether or not the quantity of labor-time contained in it is the quantity necessarily required by society for the production of a quarter of wheat. The commodity as such is an exchange value, it has a price. In this difference between exchange value and price lies the demonstration of the fact that the particular individual labor contained in a commodity has first to be expressed through the process of alienation in terms of its counterpart, i. e. as impersonal, abstract, universal and, only in that form, social labor, viz. money. Whether it can be so expressed seems to be a matter of chance. Thus, although the exchange value of a commodity finds only ideally a distinct expression in price, and the twofold character of labor contained in the commodity exists as yet merely as two distinct forms of expression, and, although in consequence thereof, the embodiment of universal labor-time, gold, confronts actual commodities only as an imaginary measure of value, yet the fact that exchange value exists as price, or that gold exists as a measure of value implies the necessity of the alienation of commodities for hard cash and the possibility of their non-alienation. In short, here lies latent the entire contradiction which is inherent in the fact that products are commodities or that the particular work of a private individual can be of no account in societyPg 82 until it has taken the very opposite form of abstract universal labor. For that reason, the utopians, who want to have commodities but not money, who want a system of production based on private exchange without the necessary conditions underlying such a system, are consistent when they "destroy" money not in its tangible form but in its nebulous illusory form of a measure of value. Under the invisible measure of value there lurks the hard cash.
The process by which gold has become the measure of value and exchange value has been turned into price, being once assumed, all commodities express in their prices but imagined quantities of gold of various magnitudes. As such various quantities of the same thing, gold, they are equated, compared and measured with each other, and thus arises the technical necessity of referring them to a definite quantity of gold as a unit of measure, a unit which develops into a standard measure by virtue of its divisibility into aliquot parts, which in their turn can be sub-divided into aliquot parts.40 But quantities of gold as such are measured by weight.
The standard of measure is thus found ready in the general measures of weight of metals and, therefore, where-ever metallic circulation is in vogue, these measures serve originally as standards of price. Since commodities no more relate to each other as exchange values to be measured by labor-time, but as magnitudes of the same denomination measured in gold, the latter is transformed from a measure of value into a standard of price. The comparison of prices with each other as different quantities of gold is thus crystallized in figures which correspond to an assumed quantity of gold and represent it as a standard of aliquot parts. Gold as measure of value and as standard of price has entirely different forms of manifestation and the confusing of the two has resulted in the wildest of theories. Gold is a measure of value as incorporated labor-time; it is the standard of price as certain weight of metal. Gold becomes the measure of value by virtue of its relation as exchange value to commodities as exchange values; as standard of price, a definite quantity of gold serves as a unit for other quantities of gold. Gold is the measure of value, because its value is variable; it is the standard of price, because it is fixed as a constant unit of weight. In this case, as in all cases of measuring quantities of the same denomination, the establishment of a definite and unvarying unit of measure is all-important. The necessity of settling upon a quantity of gold as a unit of measure and upon its aliquot parts as subdivisions of that unit, has given rise to the notion that a certain quantity of gold which has naturally a variable value had been assigned a fixed ratio of valuePg 84 to the exchange values of all commodities; the fact is overlooked that exchange values of commodities are transformed into prices, i. e. into quantities of gold, before gold develops as a standard of price. No matter how the value of gold may vary, the ratios between the values of different quantities of gold remain constant. Let the fall in the value of gold amount to 1000 per cent., still twelve ounces of gold will have a twelve times greater value than one ounce of gold; and in prices the only thing considered is the ratio between different quantities of gold. Since, on the other hand, no rise or fall in the value of an ounce of gold can alter its weight, no alteration can take place in the weight of its aliquot parts. Thus gold always renders the same service as an invariable standard of price, no matter how much its value may vary.41
An historical process which, as we shall explain later, was determined by the nature of metallic circulation, led to the result that the same denomination of weight was Pg 85retained for a constantly changing and decreasing weight of precious metals in their function of a standard of price. Thus the English pound sterling denotes less than one-third of its original weight; the pound Scot, before the Union, only 1-36; the French livre, 1-74; the Spanish Maravedi, less than 1-1000; the Portuguese Rei, a still smaller fraction. Such was the historical origin of the discrepancy between the current money names of various weights of metals and their weight denominations.42 Since the determination of the unit of measure, of its aliquot parts, and of their names is purely conventional, and since they should possess within the sphere of circulation the character of universality and compulsion, they had to be settled by law. The purely formal operation thus devolved upon the government.43 The metal which was to serve as the money maPg 86terial, was found already adopted in the community. In different countries the legal standard of price is naturally different. In England e. g. the ounce as a weight of metal is divided into pennyweights, grains and carats Troy, but the ounce of gold as the unit of money is divided into 3 7-8 sovereigns, the sovereign into 20 shillings, the shilling into 12 pence, so that 100 pounds of 22 carat gold (1200 ounces) = 4672 sovereigns and 10 Pg 87shillings. In the world market, however, where national boundaries disappear, these national characteristics of the measure of money also disappear and give place to the general measures of weight of metals.
