Origin & History of “coin”
Latin cuneus meant ‘wedge’ (from it we get cuneiform ‘wedge-shaped script’). It passed into Old French as coing or coin, where it developed a variety of new meanings. Primary amongst these was ‘corner-stone’ or ‘corner’, a sense preserved in English mainly in the now archaic spelling quoin. But also, since the die for stamping out money was often wedge-shaped, or operated in the manner of a wedge, it came to be referred to as a coin, and the term soon came to be transferred to the pieces of money themselves.
