"The insidious crime of secretly or surreptitiously altering the monetary laws of a state - than which no more dastardly or fatal blow can be dealt at its liberties - is not a new one.

In a later age, Pliny, who justly calls it 'a crime against mankind, ' evidently refers to that alteration of the Roman mint code by which what remained of the nummulary system of the Republic was subverted, about B.C. 200, in favor of the authorised private coinages of the gentes."
