About $6 for its silver content
The value of a silver dollar based on its silver content can vary depending on the current market price of silver. Silver dollars minted before 1965 typically contain 90% silver and 10% copper, which gives them intrinsic value beyond their face value. You can determine the approximate silver content value by multiplying the weight of the coin by the current price of silver per ounce.
If the silver content is that pure, then it's some kind of silver bullion round rather than a coin used for spending. As of 18 July 2012, silver is worth $27.18 per ounce.
A 1901 silver or dollar is also known as a Morgan Silver Dollar. It is ninety percent silver and usually worth at least forty dollars even in poor condition.
