Based on the provided information, the coin you are referring to is the 1971 Eisenhower Dollar, as there was no "Liberty" design silver dollar minted in that year. The value of a 1971 Eisenhower Dollar depends heavily on which version of the coin you have.
The U.S. Mint produced two distinct types of Eisenhower dollars in 1971. The most common version was made for circulation and is composed of a copper-nickel clad. These coins, which do not contain any silver, were minted in Philadelphia (no mint mark) and Denver ("D" mint mark). If these coins show signs of wear from circulation, they are typically worth only their face value of one dollar. In pristine, uncirculated condition, they may be worth a few dollars more to collectors.
The second type is a special collector's version struck at the San Francisco Mint, identifiable by an "S" mint mark. These coins were not intended for circulation and were produced in two finishes: uncirculated (often called "Blue Ikes" from their packaging) and proof (with a mirror-like finish, from "Brown Ikes" sets). These "S" mint coins are composed of 40% silver. Their base value is tied to the melt value of their silver content, but they can be worth significantly more to collectors, especially if they are in high-grade condition.
To determine the value of your 1971 dollar, you must first identify whether it has an "S" mint mark, which indicates it is the 40% silver version. If it has no mint mark or a "D," it is the common clad coin with minimal value over face value unless it is in perfect condition.
