It depends what kind of coin you have.
If you have a small (26.5 mm) coin with a really unattractive picture of Susan B. Anthony on the front, it's copper-nickel rather than silver and is only worth $1.
If you have a large (40 mm) coin with Miss Liberty walking in a flowing gown and the words 1 oz FIne Silver or similar on the back, it's a bullion piece sold for its silver content and not for spending; the $1 denomination is artificial. In that case its value will change along with the price of silver. As of 12/2009 that's about $17.
A. The coin you are referring to is a PEACE dollar. This coin is 90% silver and worth its silver value, unless graded by a third party or in mint state. a standard fine condition coin is not worth anything over spot price of silver.
It is 40% silver and worth about $5 in scrap silver regardless of condition.
A 1969 silver Kennedy half dollar is worth $5 inn perfect condition. The value of the silver is worth $2.87.
Currently as of April 2012 a 1880 Morgan silver dollar in MS63 uncirculated condition is worth around 63 dollars.
The 1924 silver dollar is called a Peace dollar because it says Peace on the side with the eagle. It is worth about $25 for the silver alone. If the condition is better, it is worth more.
