A true discovery to the commons of England : how they have been cheated of almost all the gold and silver coyn of this nation, which hath been, and is daily transported into forraign parts. And how the people of this nation are, and have been abused by light and clipped English money, and the means shewed for the prevention thereof. Humbly presented to the Parliament of the Common-wealth of England. By Thomas Violet a true lover of his countrey.
