What is the value of eisenhauer silver dollars?

To clarify, that's Eisenhower, not "eisenhauer", and copper-nickel, not silver.

Any that you find in circulated condition are worth face value to $1.15

Proof or uncirculated ones in their original packages, or any of the special collectors' edition pieces struck in 40% silver, will be worth more. In that case please post a new question with the coin's date and what mint mark letter, if any, is above the date.
