silver lasted from the passage of the Fourth Coinage Act in 1873, which demonetized silver and was called the "Crime of '73" by opponents, until 1963, when the Silver Purchase Act of 1934, which allowed the U.S. President and U.S Department of Treasury to regulate U.S silver, was completely repealed by Public Law 88-36. Definitions and explanation Under the gold specie standard, anyone in possession of gold bullion could deposit it at a mint where it would then be processed into gold coins. Less a nominal seigniorage to cover processing costs, the coins would then be paid to the depositor; this was free coinage of gold by definition. The objective of the free silver movement was that the mints should accept and process silver bullion according to the same principle, although the market value of the silver in circulating coins of the United States was substantially less than face value. As a result, the monetary value of silver coins was based on government fiat rather than on the commodity value of their contents, and this became especially true following the huge silver strikes in the West, which further depressed the silver price. From that time until the early 1960s the silver content in United States dimes, quarters, half-dollars, and silver dollars was worth only a fraction of their face values. Free coinage of silver would have amounted to an increase in the money supply, resulting in inflation. Response Many populist organizations favored an inflationary monetary policy because it would enable debtors (often farmers who had mortgages on their land) to pay their debts off with cheaper, more readily available dollars. Those who would suffer under this policy were the creditors such as banks and landlords. The most vocal and best-organized supporters were the silver mine owners (such as William Randolph Hearst) and workers, and the western states and territories generally, as most U.S. silver production was based there and the region had a great number of highly indebted farmers and ranchers. Outside the mining states of the West, the Republican Party steadfastly opposed free silver, arguing that the best road to national prosperity was "sound money", or gold, which was central to international trade. They argued that inflation meant guaranteed higher prices for everyone, and real gains chiefly for the silver interests. In 1896 Senator Henry M. Teller of Colorado led many western Republicans to bolt and form a third
