"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. There is a suggestion in the decree of B.C. 360, concerning the ancient iron money of Sparta, that Gylipus was not unfamiliar with this grave offence. 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." Despite its title, referring to a mistress of Charles II of England, this 1899 work mainly deals with America.
