Circulation-strike Eisenhower dollars are technically not "silver" dollars because they're made of copper-nickel.
Some collectors' coins were struck in 40% silver alloy and were sold in special packaging. They were made by the San Francisco Mint so they have an "S" mintmark.

Half dollars dated 1964 and earlier are 90% silver and are worth about $11 in silver content. Keep in mind that proof, error, and key date coins may be worth much more than pure silver content. And from 1965-1970 the half dollar was 40% silver and is worth about $4.50 in silver content. Half dollars dated 1971 and later are not silver unless found in a US mint silver proof set. Note that any half dollar made during 1965-69 is only partially silver and is worth about $3. Halves dated 1971 and later contain NO silver and are only worth 50 cents.
