That's a very broad question. To determine a specific value you have to know the coin's date, mint mark, and condition. Without those facts, it's not possible to even give a ballpark answer because the coins' values could range from their silver melt value (about $3.25 as of 05/2010) to thousands of dollars for a high-grade rare one such as a 1932-S or 1932-D.
