Rh as so far developed, is that, the value of gold being given, the quantity of money in circulation will be determined by the prices of commodities. Thus, at a given moment, the quantity of gold in circulation in a country is simply determined by the exchange value of the commodities in circulation. Let us suppose now that the sum total of these exchange values has declined either because there are less commodities produced at the old exchange values, or because, in consequence of an increased productivity of labor, the same quantity of commodities has a smaller value. Or, we may assume on the contrary that the sum total of exchange values has increased, either because the quantity of commodities has increased while the cost of their production has remained the same, or because the value of the same or of a smaller quantity of commodities has risen in consequence of a diminished productivity of labor. What becomes in either case of the given quantity of metal in circulation? If gold is money merely because it is current as a medium of circulation; if it is compelled to remain in circulation like government legal tender paper money (and that is what Ricardo has in mind), then the quantity of money in circulation will rise above the normal level, as determined by the exchange value of the metal, in the former case, and fall below that level in the latter. Although possessing a value of its own, gold will become in the former case a token of a metal of lower exchange value than its own, and in the latter, a token of a metal of higher value. In the former ease it will remain as a token of value less than its own, in the latter greater than
