the relation of direct barter _within the process of circulation_ and that their relative values are ascertained through their exchange as simple commodities. The illusion that gold is bartered as a simple commodity for other commodities in the process of circulation is due to the fact that prices represent equations in which certain quantities of commodities are made equal to certain quantities of gold, i. e., that the commodities are made to relate to gold in its capacity of money, as a universal equivalent, and, therefore, appear to be directly exchangeable for it. In so far as the price of a commodity is _realized_ in gold, it is exchanged for gold as a commodity, as a particular embodiment of labor-time; but in so far as it is the _price_ that is realized in gold, the commodity is exchanged for gold in its capacity of money and not of a commodity, i. e., it is exchanged for gold as a universal embodiment of labor-time. But in either case the quantity of gold for which the commodity is exchanged in the process of circulation is not determined by exchange, but the exchange is determined by the price of the commodity, i. e., by its exchange value estimated in gold.[67] Within the process of circulation gold appears in everybody’s hands as the result of sale C―M. But since C―M, sale, is at the same time M―C, purchase, it is apparent that while C, the commodity from which the process starts, is passing through its first metamorphosis, another commodity, which confronts it as the opposite pole M, is completing its second metamorphosis and is, therefore, passing through the second phase of circulation, while the first commodity is still in the first phase of its course. As a result of the first phase of circulation, the sale, we get money which is the starting point of the second phase. In place of the commodity in its first form appears its golden equivalent. This result may now form a resting point, since the commodity in this second form possesses a lasting existence of its own. The commodity, a non-use-value in the hands of its possessor, is now on hand in an always useful, since always exchangeable, form, and it depends upon circumstances when and at what point of the surface of the commodity world it will again enter circulation. Its formation into a gold chrysalis constitutes an independent period in its life which may last a greater or less length of time. While in the case of barter the exchange of one particular use-value is directly bound up with the exchange of another particular use-value, the universal character of labor which creates exchange value is manifested in the separation and lack of coincidence of acts of purchase and sale.
