The most unique quality of money is its general acceptability. Money is accepted by people in exchange for goods and services because it is generally recognized and agreed upon as a medium of exchange. Unlike other items that may be used for exchange such as gold, diamonds, or other commodities, money has no intrinsic value, but it is valuable because people accept it as payment for goods and services. This makes it a universally accepted means of exchange, and one of the most important functions of money.
