Bimetallism, also known as the bimetallic standard, is a monetary standard in which the value of the monetary unit is defined as equivalent to certain quantities of two metals, typically gold and silver, creating a fixed rate of exchange between them.

Free silver was a major economic policy issue in the United States in the late 19th century. Its advocates were in favor of an expansionary monetary policy featuring the unlimited coinage of silver into money on-demand, as opposed to strict adherence to the more carefully fixed money supply implicit in the gold standard. Free silver became increasingly associated with populism, unions, and the perceived struggle of ordinary Americans against the bankers, monopolists, and robber barons of the Gilded Age. Hence, it became known as the "People's Money".
