What does bimetallism mean?
Bimetallism is a monetary system in which two metals — historically gold and silver — are recognized as legal tender simultaneously, with their relative values fixed by law at a set ratio. The idea was that allowing both metals to circulate freely would stabilize prices and expand the money supply. In practice, maintaining a fixed ratio proved difficult: whenever the market value of one metal diverged significantly from its official rate, that metal tended to disappear from circulation, a phenomenon explained by Gresham's law ('bad money drives out good'). Bimetallism dominated monetary policy debate in much of Europe during the nineteenth century and became especially contentious in the United States, where advocates of the free coinage of silver clashed with supporters of the gold standard in the 1890s. Today the word survives mainly in economic history, referring to this system and to the political movements built upon it.
nounThe use of two metals, especially gold and silver, as a joint monetary standard, with a fixed ratio between their values. More broadly, a monetary system based on two legal-tender metals.
- A monetary system in which two metals, usually gold and silver, serve as legal tender at a fixed value ratio.
- (Historical/political context) The late-19th-century political movement advocating the free coinage of silver alongside gold.
"The election of 1896 in the United States turned largely on the question of bimetallism versus the single gold standard."
"Under strict bimetallism, both gold and silver coins circulated at a legally fixed exchange ratio."
"Critics argued that bimetallism would drive the scarcer metal out of circulation through Gresham's law."
Rarely pluralized; the concept is treated as uncountable, though a plural can occasionally appear when referring to different historical systems of bimetallism in different countries or periods.
"Historians have compared the various national bimetallisms of the nineteenth century."
In the 1896 US presidential election, 'bimetallism' was so politically explosive that William Jennings Bryan built an entire campaign around it — and lost.

Etymology of bimetallism
Bimetallism derives from the prefix bi- (Latin bis, meaning 'twice') combined with 'metallism', from Greek metallon, meaning 'mine' or 'metal'. The term arose in the mid-nineteenth century as economists sought to describe systems using two metallic currencies side by side. Its cognate 'bimetallic' shares the same roots, while 'monometallism' was coined in parallel to denote a one-metal standard.

How bimetallism is actually used
Bimetallism is a technical term from economics and monetary history, used almost exclusively in formal, academic, or historical contexts. It carries no strong connotation on its own, though it is strongly associated with late-19th-century debates over the gold standard, particularly in Britain after 1816 and in the United States during the 'Free Silver' era. It is rarely encountered in everyday conversation.
Easily confused with bimetallism
Bimetallism is a monetary standard based on two metals (typically gold and silver) at a fixed ratio, whereas monometallism bases currency on a single metal alone.
