The Theory of Money and Credit - Ludwig von Mises [24]
Exactly the same sort of significance was enjoyed by the Reich Treasury notes, of which not more than 120 million marks' worth were allowed to be in circulation. These also (sec. 5 of the act of April 30, 1874) were always cashed for gold by the Reichsbank on behalf of the Treasury. It is beside the point that the Treasury notes were not legal tender in private transactions while everybody was obliged to accept silver coins in amounts up to twenty marks and nickel and copper coins in amounts up to one mark; for, although they were not legally bound to accept them in settlement of debts, people in fact accepted them readily.
Another example is afforded by the German thaler of the period from the introduction of the gold standard until the withdrawal of the thaler from circulation on October 1, 1907. During the whole of this period the thaler was undoubtedly legal tender. But if we seek to go behind this expression, whose juristic derivation makes it useless for our present purpose, and ask if the thaler was money during this period, the answer must be that it was not. It is true that it was employed in commerce as a medium of exchange; but it could be used in this way solely because it was a claim to something that really was money, that is, to the common medium of exchange. For although neither the Reichsbank nor the Reich nor its separate constituent kingdoms and duchies nor anybody else was obliged to cash them, the Reichsbank, acting on behalf of the government, always took pains to ensure that no more thalers were in circulation than were demanded by the public. It achieved this result by refusing to press thalers on its customers when paying out. This, together with the circumstance that thalers were legal tender both to the bank and to the Reich, was sufficient to turn them in effect into drafts that could always be converted into money, with the result that they circulated at home as perfectly satisfactory substitutes for money. It was repeatedly suggested to the directors of the Reichsbank that they should cash their own notes not in gold but in thalers (which would have been well within the letter of the law) and pay out gold only at a premium, with the object of hindering the export of it. But the bank steadily refused to adopt this or any proposal of a similar nature.
The exact nature of the token coinage in other countries has not always been so easy to understand as that of Germany, whose banking and currency system was fashioned under the influence of such men as Bamberger, Michaelis, and Soetbeer. In some legislation, the theoretical basis of modern token-coinage policy may not be so easy to discover or to demonstrate as in the examples already dealt with. Nevertheless, all such policy has ultimately the same intent. The universal legal peculiarity of token coinage is the limitation
