Short answer: At least one dollar, but possibly much more.
There are several different types of US "silver dollars" -- more information is needed.
For Eisenhower dollars (1971 through 1978) the ones from circulation did not contain any silver even though people mistakenly call them silver dollars -- they're worth about $1.10 apiece.
As for Morgan and Peace dollars (1870's through 1930's), it could be anywhere from about $30 for a common date poor condition coin (silver value), to thousands of dollars for a nice rare date coin. More information is needed to give any kind of evaluation -- date, mintmark, condition.
Then there are the silver bullion dollar coins minted from 1986 to present. These coins were never put into circulation, although it's possible someone could accidentally spend one for face value. Like other coins, their collectible value depends on date and condition, although most of these are found in high Mint State or high Proof conditions.
Older dollar types will be worth significantly more, but exact details of the coin would be necessary for an evaluation.
You need to post a new question with more information - the date, condition, and mint mark are the most important factors in determining a coin's value. Without that information it's not possible to provide any evaluation.Not nearly enough information.
Post a new question with the coin's date and mint mark.
Simply put about $30, but it could be worth a lot more depending on date and condition. An average circulated Silver Dollar coin is worth about the silver content.
