Sweat

To sweat coin. To subtract part of the silver or gold by friction, but not to such an amount as to render the coin useless as a legal tender. The French use suer in the same sense, as “Suer son argent,” to sweat his money by usury. “Vous faites suer le bonhomme—tel est votre dire quand vous le pillez.” (Harangue du Capitaine la Carbonnade.) (1615.)
