Money. A standard of value and medium of payment established by law.  In the United States the
term money means gold, silver, nickel and bronze coins, gold certificates, silver certificates,
Treasury notes (issued for the purchase of silver bullion under the so-called Sherman act), United
States notes (greenbacks) and National bank notes (issued by national banks). Other
synonymous terms are cash and currency.  The most important attribute of any form of money is
its legal tender power, by which is meant the power conferred by law to discharge a debt payable
in money. Gold alone possesses by virtue of commercial usage the unlimited legal tender quality
throughout the civilized world. The value, that is, the purchasing power, of gold is the same
throughout the world.
