or Folis, anciently signified a little bag or purse; whence it came to be used for a sum of money, and very different sums were called by that name: thus the scholiast on the Basilics mentions a follis of copper which was worth but the 24th part of the millarenis; the gloriae nomiae, quoted by Gronovius and others, one of 125 millarenes, and another of 250 denarii, which was the ancient sestertium; and three different sums of eight, four, and two pounds of gold, were each each called follis. According to the account of the scholiast, the ounce of silver, which contained five milliareses of 60 in the pound, was worth 120 folles of copper. The gloffographer, describing a follis of 250 denarii, says it was equal to 312 pounds 6 ounces of copper; and as the denarius of that age was the 8th part of an ounce, an ounce of silver must have been worth 120 ounces of copper; and therefore the scholiast's follis was an ounce of copper, and equal to the gloffographer's nummus. But as Constantine's copper money weighed a quarter of a Roman ounce, the scholiast's follis and the gloffographer's nummus contained four of them, as the ancient nummus contained four asses.
