means Small, flat pieces of metal stamped to a standard value and used as money.
from From Old French 'coin' (also spelled 'coing'), meaning a wedge, corner, or angle — itself from Latin 'cuneus,' a wedge (the same root behind 'cuneiform,' the wedge-shaped writing). The wedge in question was the die used to strike the metal: the sharp tool that punched the design left its name on the punched product. So a coin is, etymologically, a thing made by a wedge — the stamp came first, and the money took its name from the tool that marked it.
