The Peace Dollar was originally made to replace the Morgan Silver Dollar in 1921. In order to find a design to replace the Peace Dollar, the United States Commission for Fine Arts held a contest with eight artists to find a design to symbolize peace after the world war had just ended. Ultimately Anthony D. Francisci was chosen to design the next silver dollar. He was given one task, create a silver dollar that symbolizes peace. As a result, the obverse of the Peace Dollar featured a goddess of liberty with the word "liberty" above her head. The reverse of the coin featured a fierce looking bald eagle. The bald eagle can be seen grasping a olive branch as it sits perched on a rock. The olive branch is one of the world's oldest signs of peace.
The 1928 Peace Dollar is the lowest mintage in the entire series with only 360,649 coins ever minted. It is the rarest among all the 1928 Peace Dollars produced that year. Even more rare than the 1928-S Peace Dollar. No Denver Peace Dollar was ever minted in 1928. In brilliant uncirculated condition this coin can currently be found for around $800-$900. However, if you try to find a high end gem brilliant uncirculated coin it can cost you tens of thousands of dollars.
The Peace Dollar was created to replace the 1921 Morgan Silver Dollar after the world war had ended. Its first year featured a high relief, but was quickly changed as that was found to be impractical in circulation. As a result the rest of the Peace Dollar series was made as a standard relief. Many collectors love the 1921 Peace Dollar because it is the only high relief ever made in the series. All the features of the coin can be seen elevated off the surface and its quite beautiful.
