The silver and copper tokens which represent gold coin in certain spheres of circulation in the interior of the country, contain a definite quantity of silver and copper prescribed by law, but after they get into circulation, they wear off like gold coins and become even more rapidly mere phantoms, according to the rapidity and steadiness of their circulation. To draw again a line of demonetization beyond which silver and copper tokens would lose their character of coins, they would have to be Pg 148replaced in turn within certain spheres of their own circulation by some other symbolic money, say iron and lead, and such representation of one kind of symbolic money by another kind would form an endless process. In all countries with a well developed circulation the very requirements of money circulation make it necessary that the character of silver and copper tokens as money be made independent of any loss of weight in those coins. Thus, as it was in the nature of things, it appears that they serve as symbols of gold coin not because they are symbols made of silver or copper, not because they have certain value, but only in so far as they have no value.
Relatively worthless things, such as paper, can consequently perform the function of symbols of gold money. That subsidiary currency consists of metal tokens, such as silver, copper, etc., is mainly due to the fact that in most countries the less valuable metals such as silver in England, copper in ancient Rome, Sweden, Scotland, etc., had circulated as money before they were degraded by the process of circulation to the rank of small change and replaced by a more precious metal. Besides, it is natural that the money symbol which grows directly out of metallic circulation, should itself be a metal. Just as that portion of gold which would always have to circulate as small change, is replaced by metal tokens; so can the other portion of gold which is constantly absorbed as coin by circulation in the interior of the country and, therefore, must continually circulate, be replaced with worthless tokens. The level below which the mass of circulating coin never sinks is determined in eachPg 149 country by experience. Thus, the originally imperceptible difference between the nominal weight and the metallic weight of a metal coin can grow apace until it reaches the point of absolute separation. The mint name of money parts company with its substance and exists outside of it in worthless slips of paper. Just as the exchange value of commodities is crystallized by their process of exchange into gold money, so is gold money sublimated in its currency into its own symbol first in the form of worn coin, then in the form of subsidiary metal currency, and finally in the form of a worthless token, paper, mere sign of value.
Gold coin has produced its substitutes, first metallic and then paper, only because in spite of its loss of metallic weight it continued to perform the function of coin. It did not circulate because of its wear and tear; on the contrary, it wore out to a symbol because it continued to circulate. Only in so far as gold money becomes simply a token of its own value in the process of circulation, can mere tokens of value take its place.
In so far as the movement C—M—C represents a dynamic unity of two processes C—M and M—C which pass directly one into the other, or in so far as a commodity passes through the complete process of its metamorphosis, it express its exchange value in price and in money only to discard that form at once and to become again a commodity or, rather, a use-value. That is to say, it develops only an apparent assertion of the independence of its exchange value. On the other hand, we have seen that gold, in so far as it performs the function of coin or in so far as itPg 150 continually circulates, actually forms only a connecting link between the metamorphoses of commodities and constitutes but their transitory money form; furthermore, that it realizes the price of one set of commodities only in order to realize that of another, but in no case does it constitute a stable form of exchange value or appear itself as a commodity in a state of rest. The reality which the exchange value of commodities acquires in the process and which is represented by gold in its circulation, is the reality of an electric spark. Although real gold, it plays the part of fictitious gold, and can, therefore, be replaced in this function by a token of itself.
The token of value, say paper, which plays the part of coin, is the token of a quantity of gold expressed in its currency name, i. e., it is a gold token. Just as a certain quantity of gold does not in itself express a value ratio, so is that true of the token which takes its place. In so far as a certain quantity of gold, as embodied labor-time, has a value of a certain magnitude, the gold token represents value. But the magnitude of the value which it represents depends all the time on the value of the quantity of gold for which it stands. As regards commodities the token of value expresses the reality of their price, it is signum pretii and sign of their value only because their value is expressed in their price. In the process C—M—C, in so far as it represents the dynamic unity or direct alternation of the two metamorphoses—and that is the aspect it assumes in the sphere of circulation in which the token of value discharges its function—the exchange value of commodities acquires inPg 151 price only an ideal expression and in money only an imaginary symbolic existence. Exchange value thus acquires only an imaginary though material expression, but it has no real existence except in the commodities themselves, in so far as a certain quantity of labor-time is embodied in them. It appears, therefore, that the token of value represents directly the value of commodities, by figuring not as a token of gold but as a token of the value which exists in the commodity alone and is only expressed in price. But it is a false appearance. The token of value is directly only a token of price, i. e., a token of gold, and only indirectly a token of value of a commodity. Unlike Peter Shlemihl, gold has not sold its shadow, but buys with its shadow. The token of value operates only in so far as it represents the price of one commodity as against that of another within the sphere of circulation, or in so far as it represents gold to every owner of commodities. A certain comparatively worthless object such as a piece of leather, a slip of paper, etc., becomes by force of custom a token of money material, but maintains its existence in that capacity only so long as its character as a symbol of money is guaranteed by the general acquiescence of the owners of commodities, i. e., so long as it enjoys a legally established conventional existence and compulsory circulation. Paper money issued by the state and circulating as legal tender is the perfected form of the token of value, and the only form of paper money, which has its immediate origin in metallic circulation or even in the simple circulation of commodities. Credit money belongs to a higher sphere of the social process of production and is govPg 152erned by entirely different laws. Symbolic paper money does not in fact, differ in the least from subsidiary metal coin, except that it reaches wider spheres of circulation. We have seen that the mere technical development of the standard of price or of the mint price and later the shaping of gold bullion into coin have called forth the interference of the state; this circumstance brought about a visible separation of national circulation from the world circulation of commodities: this separation is completed by the evolution of coin into a token of value. As a mere medium of circulation money can assume an independent existence only within the sphere of national circulation.80
