coin

coin: [14] 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.
=> quoin

coin (n.)

c. 1300, "a wedge," from Old French coing (12c.) "a wedge; stamp; piece of money; corner, angle," from Latin cuneus "a wedge." The die for stamping metal was wedge-shaped, and the English word came to mean "thing stamped, a piece of money" by late 14c. (a sense that already had developed in French). Compare quoin, which split off from this word 16c. Modern French coin is "corner, angle, nook." Coins were first struck in western Asia Minor in 7c. B.C.E.; Greek tradition and Herodotus credit the Lydians with being first to make and use coins of silver and gold.

coin (v.)

"to coin money," mid-14c., from coin (n.). Related: Coined; coining. To coin a phrase is late 16c. A Middle English word for minter was coin-smiter.
