The black and silver products of the laborers, which in the form of commodities are easily divided into buyers’ necessaries, or by means of exchange between commodities, have in themselves no value, except in so far as they can be sold at their value.

The fact that they can be bought at a great sacrifice of their value does not prevent them from constituting a part of the constant capital of the capitalist. They form part of the commodity-supply and are, so to say, circulating on its front.

We shall not discuss this point any further until later.
