Support for bimetallism grew in the 1870s, and resulted in the passage of the Bland–Allison Act of February 28, 1878, over the veto of President Rutherford B. Hayes. This legislation required the Treasury to purchase millions of dollars' worth of silver bullion each month, and coin it into silver dollars—the denomination was restored as a legal tender, except when gold was specified by law or private contract. Renewed support for silver led to the passage of the Sherman Silver Purchase Act of 1890, greatly increasing the silver purchases, and requiring the Treasury to pay for them in banknotes that could be redeemed for gold. Over the next three years, $132,000,000 in gold was withdrawn from the Treasury, and amid another depression President Grover Cleveland secured the repeal of the silver purchase act.
