Note 12 — Chapter IX · THE EUPHRATES FRONTIER AND THE PARTHIANS.
William P. (William Purdie) Dickson translation
Usually this is restricted to the large silver money, and the small silver and most of the copper are regarded as of royal coinage. But by this view a singular secondary part in coinage is assigned to the great-king. More correctly perhaps the former coinage is conceived of as predominantly destined for dealings abroad, the latter as predominantly for internal intercourse; the diversities subsisting between the two kinds are also explained in this way.
