While the provided search results confirm that collector's guides for the 1971 Eisenhower dollar exist, they do not contain the specific textual information needed to determine its value. Based on general numismatic knowledge, the answer can be provided.
The value of a 1971 Eisenhower uncirculated silver dollar depends on several factors, but it's important to first identify the correct coin. The only 1971 Eisenhower dollars that contain silver were struck at the San Francisco Mint and bear an "S" mint mark. These were specifically created for collectors and were not intended for circulation. These coins are composed of 40% silver.
The uncirculated version of the 1971-S Eisenhower dollar was sold by the U.S. Mint in a blue envelope, earning it the nickname "Blue Ike." A standard, ungraded example in its original blue government packaging typically has a value in the range of $10 to $15. This value is influenced by the coin's base silver content, known as its melt value, plus a numismatic premium paid by collectors. The price can fluctuate with the market price of silver.
For coins that have been professionally graded by a third-party service, the value can increase substantially based on the assigned grade. While most examples fall into a common grade range, a 1971-S uncirculated silver dollar in a very high state of preservation, such as MS-67 or higher, can be worth hundreds of dollars due to its rarity in such pristine condition.
