Bearing the English crown mark in accordance with the 1765 stamp act which was one fundamental cause of the American Revolution. The Stamp Act required that a revenue stamp by place on all documents including playing cards and dice by extension in order to fund the English Army of 10,000 troops on the Appalachian frontier. The Virginia House of Burgesses passed resolutions drafted by Patrick Henry. The issue was English taxation of the colonies for the purpose of raising money rather than regulating commerce, which most colonists believed England had no right to do. This pair, 3/8” cubical, bears the crowned GR impression, faint but unmistakable, of the revenue stamp. The stamps were always on the six pip side and remnants of red ink as well show on both dice.
