The Theory of Money and Credit - Ludwig von Mises [30]
Wherever disorganization of the coinage had advanced so far that the presence of a stamp on a piece of metal was no longer any help in determining its actual content, commerce ceased entirely to rely on the official monetary system and created its own system of measuring the precious metals. In large transactions, ingots and trade tokens were used. Thus, the German merchants visiting the fair at Geneva took ingots of refined gold with them and made their purchases with these, employing the weights used at the Paris market, instead of using money. This was the origin of the Markenskudo or scutus marcharum, which was nothing but the merchants' usual term for 3.765 grams of refined gold. At the beginning of the fifteenth century, when the Geneva trade was gradually being transferred to Lyons, the gold mark had become such a customary unit of account among the merchants that bills of exchange expressed in terms of it were carried to and from the market. The old Venetian lire di grossi had a similar origin. [16] In the giro banks that sprang up in all big commercial centers at the beginning of the modern era we see a further attempt to free the monetary system from the authorities' abuse of the privilege of minting. The clearinghouse business of these banks was based either on coins of a specific fineness or on ingots. This bank money was commodity money in its most perfect form.
The nominalists assert that the monetary unit, in modern countries at any rate, is not a concrete commodity unit that can be defined in suitable technical terms, but a nominal quantity of value about which nothing can be said except that it is created by law. Without touching upon the vague and nebulous nature of this phraseology, which will not sustain a moment's criticism from the point of view of the theory of value, let us simply ask: What, then, were the mark, the franc, and the pound before 1914? Obviously, they were nothing but certain weights of gold. Is it not mere quibbling to assert that Germany had not a gold standard but a mark standard? According to the letter of the law, Germany was on a gold standard, and the mark was simply the unit of account, the designation of 1/2790 kg. of refined gold. This is in no way affected by the fact that nobody was bound in private dealings to accept gold ingots or foreign gold coins, for the whole aim and intent of state intervention in the monetary sphere is simply to release individuals from the necessity of testing the weight and fineness of the gold they receive, a task which can only be undertaken by experts and which involves very elaborate precautionary measures. The narrowness of the limits within which the weight and fineness of the coins are legally allowed to vary at the time of minting, and the establishment of a further limit to the permissible loss by wear of those in circulation, are much better means of securing the integrity of the coinage than the use of scales and nitric acid on the part of all who have commercial dealings. Again, the right of free coinage, one of the basic principles of modern monetary law, is a protection in the opposite direction against the emergence of a difference in value between the coined and uncoined metal. In large-scale international trade, where differences that are negligible as far as single coins are concerned have a cumulative importance, coins are valued, not according to their number, but according to their weight; that
