Yet it had also its weak point. According to a custom, common in all antiquity, but which reached its highest development at Carthage[44]
, the Roman government issued along with the good silver denarii also denarii of copper plated with silver, which had to be accepted like the former and were just a token-money analogous to our paper currency, with compulsory circulation and recourse on the public chest, inasmuch as it also was not entitled to reject the plated pieces. This was no more an official adulteration of the coinage than our manufacture of paper-money, for they practised the thing quite openly; Marcus Drusus proposed in 663, with the view of gaining the means for his largesses of grain, the sending forth of one plated denarius for every seven silver ones issuing fresh from the mint; nevertheless this measure not only offered a dangerous handle to private forgery, but designedly left the public uncertain whether it was receiving silver or token money, and to what total amount the latter was in circulation. In the embarrassed period of the civil war and of the great financial crisis they seem to have so unduly availed themselves of plating, that a monetary crisis accompanied the financial one, and the quantity of spurious and really worthless pieces rendered dealings extremely insecure. Accordingly during the Cinnan government an enactment was passed by the praetors and tribunes, primarily by Marcus Marius Gratidianus[45], for redeeming all the token-money by silver, and for that purpose an assay-office was established. How far the calling-in was accomplished, tradition has not told us; the coining of token-money itself continued to subsist.As to the provinces, in accordance with the setting aside of gold money on principle, the coining of gold was nowhere permitted, not even in the client-states; so that a gold coinage at this period occurs only where Rome had nothing at all to say, especially among the Celts to the north of the Cevennes and among the states in revolt against Rome; the Italians, for instance, as well as Mithradates Eupator struck gold coins. The government seems to have made efforts to bring the coinage of silver also more and more into its hands, particularly in the west. In Africa and Sardinia the Carthaginian gold and silver money may have remained in circulation even after the fall of the Carthaginian state; but no coinage of precious metals took place there after either the Carthaginian or the Roman standard, and certainly very soon after the Romans took possession, the denarius
introduced from Italy acquired the predominance in the transactions of the two countries.In Spain and Sicily, which came earlier to the Romans and experienced altogether a milder treatment, silver was no doubt coined under the Roman rule, and indeed in the former country the silver coinage was first called into existence by the Romans and based on the Roman standard[46]
; but there exist good grounds for the supposition, that even in these two countries, at least from the beginning of the seventh century, the provincial and urban mints were obliged to restrict their issues to copper small money.Only in Narbonese Gaul the right of coining silver could not be withdrawn from the old-allied and considerable free city of Massilia; and the same was presumably true of the Greek cities in Illyria, Apollonia and Dyrrhachium. But the privilege of these communities to coin money was restricted indirectly by the fact, that the three-quarter denarius
, which by ordinance of the Roman government was coined both at Massilia and in Illyria, and which had been under the name of victoriatus received into the Roman monetary system[47], was about the middle of the seventh century set aside in the latter; the effect of which necessarily was, that the Massiliot and Illyrian currency was driven out of Upper Italy and only remained in circulation, over and above its native field, perhaps in the regions of the Alps and the Danube. Such progress had thus been made already in this epoch, that the standard of the denarius exclusively prevailed in the whole western division of the Roman state; for Italy, Sicily - of which it is as respects the beginning of the next period expressly attested, that no other silver money circulated there but the denarius - Sardinia, Africa, used exclusively Roman silver money, and the provincial silver still current in Spain as well as the silver money of the Massiliots and Illyrians were at least struck after the standard of the denarius.
