The silver dollar was widely used in the United States until the early 20th century. However, the passage of the Pittman Act of 1918, which authorized the melting of silver dollars to produce silver bullion for World War I, significantly reduced the number of silver dollars in circulation. By the early 1930s, the silver dollar had become relatively scarce, and President Franklin D. Roosevelt issued an executive order in 1933 calling for the withdrawal of all silver dollars from circulation. The silver dollars that were withdrawn from circulation were melted down and used to produce silver bullion or other silver coins.
Today, the silver dollar is no longer used in everyday circulation, but it remains a popular collectible coin. Silver dollars are often bought and sold by coin collectors and dealers, and they can be found in coin shops and at coin shows.
