A good illustration of this truth is to be found in international trade. Money which is not dependent on artificial influences for its value, and which is not redeemable in something else, is good the world over at its actual commercial value, not at its value as fixed by any legal-tender laws. It is not the legal-tender stamp that gives a coin its value in international payments. A sovereign, an eagle, a napoleon, is constantly given and received in international trade not because of the stamp it bears, but because of the number of grains of a given fineness of gold which it contains--the value of which is determined in the markets of the world. And an enormous trade among the great commercial countries goes on easily and effectively without regard to the legal-tender laws of the particular country whose coins are used. By imposing the attribute of legal tender, however, upon a given metal or money, it may be believed that thereby a new demand is created for that metal, and that its value is thus controlled. And in theory there is some basis for this belief. It is, of course, true that, in so far as giving to money a legal-tender power creates a new demand for it (which without that power would not have existed) an effect upon its value can be produced. But this effect is undoubtedly much less than is usually supposed. It must be remembered that the value of gold, for instance, is affected by world influences; that its value is determined by the demand of the whole world as compared with the whole existing supply in the world. In order to affect the value of gold in any one country, a demand created by a legal-tender enactment must be sufficient to affect the world-value of gold. Evidently the effect will be only in the proportion that the new demand bears to the whole stock in the world. It is like the addition of a barrel of water to a pond; theoretically the surface level is raised, but not to any appreciable extent.
