The provided search results discuss the Eisenhower Dollar series, which primarily covers coins minted from 1971 to 1978, and therefore do not contain specific information about a 1970-dated coin.
Based on numismatic knowledge, no silver dollars were minted for general circulation in 1970. The United States had stopped producing silver dollars for circulation in 1935. The dollar coin dated 1970 is the Eisenhower dollar, but it was produced exclusively for collectors and was not released into circulation.
These 1970-S Eisenhower dollars were struck at the San Francisco Mint and contain 40% silver. They were sold to collectors in two primary formats: an uncirculated version in a blue plastic-sealed pack, commonly called a "Blue Ike," and a proof version in a hard plastic case with a brown box, known as a "Brown Ike."
The value of a 1970-S Eisenhower dollar depends on its condition and whether it is the uncirculated or proof version. Generally, these coins are valued higher than their silver melt value due to their status as a collector-only issue. In average condition, they typically trade for around $10 to $20. The final value is influenced by the coin's specific condition and the current market price of silver. It is important to note the existence of an extremely rare 1970-D prototype, but these were never issued to the public and are not found in circulation.
