Bimetallism

From Conservapedia

Bimetallism was a political movement in the second half of the 19th century in the United States that advocated the use of silver as a monetary standard in addition to gold. Farmers and debtors supported bimetallism because they felt it was inflationary and advantageous to them and the economy; silver miners in the western United States supported bimetallism to ensure the value of silver.
