On monetary issues, Blaine continued the advocacy for a strong dollar that he had begun as a Representative. The issue had shifted from debate over greenbacks to debate over which metal should back the dollar: gold and silver, or gold alone. The Coinage Act of 1873 stopped the coinage of silver for all coins worth a dollar or more, effectively tying the dollar to the value of gold. As a result, the money supply contracted and the effects of the Panic of 1873 grew worse, making it more expensive for debtors to pay debts they had entered into when currency was less valuable. Farmers and laborers, especially, clamored for the return of coinage in both metals, believing the increased money supply would restore wages and property values. Democratic Representative Richard P. Bland of Missouri proposed a bill, which passed the House, that required the United States to coin as much silver as miners could sell the government, thus increasing the money supply and aiding debtors. In the Senate, william B. Allison, a Republican from Iowa offered an amendment to limit the silver coinage to two to four million dollars per month. This was still too much for Blaine, and he denounced the bill and the proposed amendment, but the amended Bland–Allison Act passed the Senate by a 48 to 21 vote. Hayes vetoed the bill, but Congress mustered the two-thirds vote to pass it over his veto. Even after the Bland–Allison Act’s passage, Blaine continued his opposition, making a series of speeches against it during the 1878 congressional campaign season.
