The value of a 1776-1976 dated dollar coin with no mint mark is determined by its composition and condition. This particular coin is known as the Bicentennial Eisenhower Dollar, struck to commemorate the 200th anniversary of the United States Declaration of Independence.
The absence of a mint mark indicates the coin was produced at the Philadelphia Mint. The Bicentennial dollars struck in Philadelphia for general circulation were made of a copper-nickel clad composition, not silver. As a result, their value is primarily derived from their face value. For a circulated example, the worth is typically just one dollar. Even in uncirculated condition, these common clad coins command only a very modest premium above their face value.
It is essential to distinguish these clad coins from the collector versions produced during the same period. The United States Mint also issued Bicentennial Eisenhower dollars composed of 40% silver. These silver versions, however, were struck at the San Francisco Mint and are identifiable by an "S" mint mark. Due to their silver content, the "S" mint mark coins carry a higher intrinsic value based on the spot price of silver and are worth significantly more than the common copper-nickel clad coins from the Philadelphia and Denver mints. Therefore, a 1776-1976 dollar with no mint mark is a standard circulation issue with minimal numismatic value.
