Investopedia explains 'Banknote'
Originally, objects such as gold and silver were used to pay for goods and services. Eventually, they were replaced by paper money and coins that were backed by precious metals.
Currently, banknotes are backed only by the government. Although in earlier times commercial banks could issue banknotes, the Federal Reserve Bank is now the only bank in the United States that can create banknotes.
