Circulation issues, many uncirculated and proof Ikes were all struck in copper-nickel so the answer for them is "none".
Some special uncirculated and proof versions were struck in 40% silver. These were only sold in special Mint packages.
If your 1972 coin is a uncirculated example it may be worth about $5.00-$7.00 because the 1971 & 1972 issue coins were not included in the Uncirculated Mint sets sold from the Mint in those years. For the Eisenhower series, some of the coins struck at the San Francisco Mint (S Mintmark) were 40% silver. None of the Eisenhower dollars regardless of date or mintmark struck for general circulation have any silver or are worth more than face value. Only proof and uncirculated collectors coins sold from the Mint have premiums.
The 1971 Eisenhower Dollar contains 0.31 ounces of silver. However, only the San Francisco minted dollars contain any silver at all. These are marked with an S.
If it's minted in Philadelphia or Denver, it contains 0% silver. If it's from San Francisco, some versions contain 40% and others are 0%.
One dollar.

Eisenhower Dollars were first minted in 1971.Perhaps you are thinking of a 1969 half dollar. 1969 was the last year that the Kennedy Half Dollars had silver. 1965-1969 Kennedy Half Dollars contain 40% silver.

There were no 1945 silver dollars minted. Silver dollars were last minted in 1935 (end of the Peace Dollar) and the same sized coins would later be resurrected with no precious metal content in 1971 as the Eisenhower Dollar.
The Eisenhower's that have 40% silver in them dated 1971 all have an "S" Mintmark and were never released for circulation.
A 1971 Eisenhower Dollar in MS60 condition is worth: $10.00 However it's made of copper-nickel, not silver!
Dwight D. Eisenhower. But it's clad technically, not sliver.
Eisenhower Dollars made for circulation only have face value and has no silver.
The first real person on a dollar coin was President Eisenhower in 1971. No silver dollar coins have portraits of real people.
Not much I'm afraid, unless it has an "S" mintmark and is 40% silver and worth about $6.50-ish in silver content. Collector demand for Eisenhower dollars are rather low and many banks still have non-silver Ike dollars in stock if you ask for them.
