Yes they are, all "S" Mint 1971 & 1972 Eisenhower dollars are 40% silver, but ONLY for those two years. In 1973 the Mint added copper-nickel clad "S" Mint coins along with the 40% "S" Mint silver coins
The Eisenhower's that have 40% silver in them dated 1971 all have an "S" Mintmark and were never released for circulation.
None of the Eisenhower dollars (1971-1978) made for circulation have ANY silver in them. For 1971 only special collectors coins that have "S" mintmark's were struck in 40% silver.
If it is a "S" mintmark Eisenhower dollar, it's 40% silver, if not, no silver.
None of the Eisenhower dollars (1971-1978) made for circulation have ANY silver in them. For 1971 only special collectors coins that have "S" mintmark's were struck in 40% silver.
These dates are 79% silver only if they have an S mint mark. If that is the case; 1971 S= $8.50 if MS-63 $11 if PF-65 1974 S= $9 if MS-63 $13 if PF-65 All lesser conditions are only $1.
None of the Eisenhower dollars regardless of date or mintmark made for general circulation have any silver in them and most are only face value, but the Proof 1971-S Eisenhower is 40% silver and has a value of $6.00.
There are no 1971 peace silver dollars. A circulated 1971 Eisenhower dollar is worth about $2. An uncirculated one is worth about $5. A silver collectors edition (with an "S" mintmark above the date) is worth about $10.
For 1971 & 1972 only, all S mint marked coins are 40% silver. From 1973 to 1976 the S mint marked coins in the standard proof sets are clad coins, the 40% silver Ike's were sold separately but they were included in the bicentennial 3-piece silver sets. No silver Ike's were struck in 1977 or 1978.
None of the Eisenhower dollars (1971-1978) that were released into circulation had any silver! Only special collectors coins sold directly from the US Mint were made from 40% silver and all of them have S mintmarks. None of the Philadelphia or Denver minted coins contain silver. The 40% silver coins were struck only from 1971 to 1976.
All 1971 & 1972 Eisenhower "S" mintmark dollars are 40% silver. The value is about $12.00.
The ONLY 1971 Eisenhower dollar to have any silver (just 40%) is the "S" mint-marked Proof or Uncirculated coins that were sold from the US Mint. No other 1971 dated coins contain any silver.
This may get a little confusing: For 1971 & 1972 all the "S" mintmarked coins are 40% silver and were struck as Proof and Uncirculated. From 1973 to 1976 the Mint issued a Copper-Nickel "S" mintmarked Proof coin along with the 40% silver issues. No silver coins were issued in 1977 & 1978.
