standard of price or of the mint price and later the shaping of gold bullion into coin have called forth the interference of the state; this circumstance brought about a visible separation of national circulation from the world circulation of commodities: this separation is completed by the evolution of coin into a token of value. As a mere medium of circulation money can assume an independent existence only within the sphere of national circulation.[80] Our presentation has shown that the coin form of gold as a token of value differentiated from the gold substance itself, has its direct origin in the process of circulation and not in any agreement or state interference. Russia offers a striking example of the natural origin of the token of value. At the time when hides and furs played there the part of money, the conflict between the perishable and bulky nature of the material and its function as a medium of circulation resulted in the custom of replacing it by small pieces of stamped leather which thus became a kind of draft payable in hides and furs. Later on they became under the name of copecs mere tokens for fractions of the silver rouble and remained in use in some parts until 1700, when Peter the Great ordered their withdrawal in exchange for small copper coins issued by the state. Ancient writers who could observe the phenomena of exclusively metallic circulation, already took the view of coin as a symbol or token of value. That is true both of _Plato_[81] and _Aristotle_.[82] In countries where credit is not developed, as e. g. in China, legal tender paper money is found at an early date[83]. Early advocates of paper money expressly point out the fact that metallic coin is transformed into a token of value in the very process of circulation. So Benjamin Franklin[84] and Bishop Berkeley.[85]
