MODERN MONETARY SYSTEMS Third type: Bimetallism.—Gold and silversare both ac- cepted for free coinage, both are unlimited legal tender; there is a fixed and legal exchange ratio betweernthe gold and silver currencies ; notes are convertible either into gold of silver at the discretion of the Bank of Issue. “Ss. 761% ~ This system, which flourished for a considerable period —from the beginning of the 19th century until 1873—in many European and American countries and has now dis- appeared, is also called the system of the double standard. As both metals could be freely imported, exported and coined, the countries in which it was adopted possessed a basis of settlement and a standard in common with mono- metallist gold standard countries on the one hand, and with monometallist silver standard countries on the other. Fourth type: “‘limping” or incomplete Bimetallism.— Historically this is a debased form of the preceding system. The essential difference between them is the disappear- ance of the free coinage of silver. States which have adopted it no longer have a standard in common with monometallic silver exchange countries, as they have ceased to accept payments by those countries in silver, subject only to the metal being recoined. The expression “bimetallism”’ adopted in the French literature of political economy is therefore wrong even if it is qualified and corrected by the word incomplete, since there is no longer a double standard in the exact sense which satisfies the decisive test of a consideration of transactions with foreign countries. Thus the so-called in- complete bimetallist system has generally worked out as a variation on the monometallist gold standard system in spite of the fact that silver coin or at least some kinds of silver coin may have remained unlimited legal tender and that bank notes may in theory have continued to be con- vertible into silver as well as into gold. In certain countries, however, with an insufficient stock of gold the practice of restricting the convertibility of notes into silver leads to a system tantamount to a monometallic silver standard or even to a system of inconvertible paper currency (Spain before 1914).
