metal than it actually contains. The longer a coin remains in circulation, the rapidity of circulation remaining the same, or the greater its rapidity of circulation within the same period of time, the greater the discrepancy between its form as coin and its actual gold or silver substance. What remains is magni nominis umbra. The body of the coin becomes but a shadow. If at first it became heavier through the process of circulation, it now becomes lighter on account of it, but continues to represent the original quantity of gold in each single purchase or sale. The sovereign, as a fictitious sovereign, as fictitious gold, continues to perform the function of a legitimate coin. While other beings lose their idealism in contact with the outer world, the coin is idealized by practice, being gradually transformed into a mere phantom of its golden or silver body. This second idealization of metal money springing from the very process of circulation, or from the discrepancy between its nominal weight and its real weight is exploited in all kinds of coin counterfeiting practiced partly by governments, partly by private adventurers. The entire history of coinage from the beginning of the middle ages until late in the eighteenth century is nothing but a history of these two-fold and antagonistic adulterations, and Custodi's voluminous collection of writings of Italian economists turns mostly about this point.
But the fictitious importance of gold due to its function, comes in conflict with its real substance. One gold coin has lost more, another, less of its metal substance in the course of circulation, and one of them is, as a matter of fact, worth more now than the other. But
