Standard. In its relation to money standard means the measure or basis of value.
A country where gold alone is by law the basis of value has a single standard; where silver alone
is by law the basis of value the country has a single standard. Where both gold and silver are
used, the one in fixed proportion to the other, the country has a double standard or bimetallic
standard. A country using paper money alone has no standard.
