Based on the information provided, a 1972 dollar with no mint mark is an Eisenhower Dollar that was struck at the Philadelphia Mint. It is important to clarify that these specific coins, intended for general circulation, are not made of silver. They are composed of a copper-nickel clad alloy. The term "silver dollar" is a common name for the denomination, but in this case, it does not reflect the coin's metallic content.
The value of a 1972 copper-nickel Eisenhower dollar is highly dependent on its physical condition. A coin that has been used in circulation and shows signs of wear and tear is typically only worth its face value of one dollar. The vast majority of these coins fall into this category.
For a coin that is in uncirculated, or "mint state," condition, the value increases. A standard uncirculated 1972 Eisenhower dollar might be valued at approximately $5. However, for specimens in a very high state of preservation, such as those graded MS 65, the value can rise to $25 or more. There are also rarer die varieties for this year that can be worth significantly more, but these require expert examination to identify.
