coined according to an entirely different standard. Thus the money in circulation in many English colonies of North America consisted until late in the eighteenth century of Spanish and Portuguese coins, although the money of account was throughout the same as in England.46
Owing to the fact that money, when serving as the standard of price, appears under the same reckoning names as do the prices of commodities, and that, therefore, the sum of 3£ 17s. l0-1/2d. may signify, on the one hand, an ounce weight of gold, and on the other, the value of a ton of iron, this reckoning name of money has been called its mint-price. Hence, there sprang up the extraordinary notion that the value of gold is estimated in its own material, and that, in contradistinction to all other commodities, its price is fixed by the State. It was erroneously thought that the giving of reckoning names to definite weights of gold is the same thing as fixing the value of those weights.47 In so far as gold serves as one of the elements in determining price, i. e., where it performs the function of money of account, it not only has no fixed price, but has no price whatever. In order to have a price, i. e., in order to express itself in a specific commodity as a universal equivalent that other commodity would have to play the same exclusive role in the process of circulation as gold. But two commodities excluding all other commodities mutually exclude each other. Therefore, wherever gold and silver have by law been made to perform side by side the function of money or of a measure of value it has always been tried, but in vain, to treat them as one and the same material. To assume that there is an invariable ratio between the quantities of gold and silver in which a given quantity of labor-time is incorporated, is to assume, in fact, that gold and silver are of one and the same material, and that a given mass of the less valuable metal, silver, is a constant fraction of a given mass of gold. From the reign of Edward III to the time of George II, the history of money in England consists of one long
