Money is no longer convertible into gold (because the supply of gold is too unstable). The pronouncement of legal tender does not assure that a currency will be accepted. The acceptance of money rests in the mutual trust of people of acceptance by others and in the trust that the value of money will be preserved. Preserving the money value depends entirely on its relative scarcity and the control of money supply (which is the purpose of monetary policy).

The value of money does not come from any weight of precious metal, but from the amount of goods or services a dollar can buy: it is the purchasing power of money. For instance, in the late 18th century, the French assignat had to be discontinued because it never caught on as a form of money (i.e. people did not accept it as money), in spite of all the official pronouncements by the French government at the time.
