Based on the titles provided in the search context, the "1972 liberty silver dollar" is formally known as the 1972 Eisenhower Dollar. The context itself does not offer specific valuation figures, so a detailed answer must be drawn from general numismatic knowledge.
The value of a 1972 Eisenhower dollar varies significantly based on its metallic composition and the mint at which it was produced. The most common versions are the copper-nickel clad coins struck for general circulation at the Philadelphia (no mint mark) and Denver (D mint mark) mints. If these coins are worn from circulation, they are typically worth only their face value of one dollar. In pristine, uncirculated condition, they may be worth a few dollars to collectors.
However, the U.S. Mint also produced special collector versions in 1972 at the San Francisco mint, which bear an "S" mint mark. These coins contain 40% silver and were never intended for circulation. Their value is primarily determined by the spot price of silver, so their worth is always considerably more than one dollar. These 40% silver coins were issued in two finishes: a standard uncirculated version often sold in a blue envelope and a proof version with a mirror-like finish sold in a brown box.
Additionally, there are rare and valuable die varieties for the 1972 Eisenhower dollar from the Philadelphia mint. Collectors have identified three different reverse designs, known as Type 1, Type 2, and Type 3, distinguished by details on the depiction of Earth. The Type 2 reverse is a scarce variety that can command a very high price, potentially worth hundreds or even thousands of dollars depending on its condition. Therefore, to determine the exact worth of a 1972 dollar, one must identify its mint mark, assess its physical condition, and check for these specific die varieties.
