Hello there! That's a great question about a very specific and interesting coin. The provided search results discuss the Eisenhower dollars made from 1971 to 1978, but the 1970 dollar is actually a special case that wasn't released into general circulation.
The only 1970-dated dollars produced were proof coins struck at the San Francisco Mint, which are identifiable by the "S" mint mark (1970-S). These coins were exclusively sold to collectors as part of the 1970 U.S. Mint Proof Set. Because they were never intended for circulation, they are a bit more sought-after than many of the later Eisenhower dollars.
These 1970-S dollars are made of 40% silver, so their base value is tied to the current price of silver. However, since they are collector's items, they are always worth more than just their silver content. In its original government packaging, a typical 1970-S proof silver dollar is generally valued in the range of $10 to $15. The exact value can fluctuate based on the coin's condition and the current market for collectibles and silver. Coins that have been professionally graded in pristine condition can be worth significantly more.
