I assume you are referring to a U.S. Eisenhower dollar.
If it's a circulation strike (copper-colored edge) it's worth face value only.
If it's in its packaging from a mint set or proof set AND the package says "40% silver", it would be worth maybe $3.50 or $4 for its metal content.

One dollar.
If the coin is a US Kennedy half dollar dated 1974 it has no silver in it and is face value.
1895
President Eisenhower
A high grade mint state coin is about $2.50 for this date, If it's circulated spend it.

One dollar.
There's no such thing as a U.S. silver dollar coin from 1957.
If the coin is a US Kennedy half dollar dated 1974 it has no silver in it and is face value.
Please rephrase the question
1895
President Eisenhower
It's not silver. None of the 1974 Kennedy halves are silver. Just spend it.
Yes since it contains silver
A dollar
Either a "wheat penny", silver dime, silver quarter, silver half dollar, half dollar, dollar, bicentenial quarter half-dollar dollar, error coin
