The Peace Silver Dollar is a significant coin in the history of the United States currency, minted primarily as a commemorative symbol of peace after World War I. Its introduction marked the resumption of silver dollar minting in the U.S., which had paused after the last Morgan Silver Dollars were produced in 1921. The Peace Dollar itself was first issued in 1921 and continued to be minted until 1935, with a noteworthy design that reflects its era and the aspirations of the nation at the time.

### Design
- **Obverse:** The obverse side features the profile of Lady Liberty, designed by Italian-American sculptor Anthony de Francisci. Liberty is depicted in a left-facing profile, with the word "LIBERTY" at the top, the phrase "IN GOD WE TRVST" (the U in TRUST is rendered as a V, which is a classical Latin usage), and the minting year at the bottom.
- **Reverse:** The reverse showcases an eagle at rest clutching an olive branch, with the word "PEACE" inscribed on the mountain upon which the eagle is perched. Surrounding the eagle are the inscriptions "UNITED STATES OF AMERICA," "E PLURIBUS UNUM," and "ONE DOLLAR."

### Specifications
- **Metal Content:** 90% silver, 10% copper.
- **Diameter:** 38.1 mm.
- **Weight:** 26.73 grams.
- **Mint Marks:** Produced at the Philadelphia (no mint mark), Denver (D), and San Francisco (S) mints. The mint mark is found on the reverse, beneath the word "ONE," before the tail of the eagle.

### Historical Context
- The Peace Dollar was introduced to celebrate the peace that followed World War I. Its issuance coincided with the end of the "Great War" and the beginning of a hopeful era for the United States.
- The coin came to replace the Morgan Silver Dollar, with a push from numismatists and the general public who desired a coin that symbolized peace.
- Anthony de Francisci's design was selected through a competition, with his depiction of Liberty modeled after his wife, Teresa.

### Collectibility and Value
- **Key Dates:** Certain years and mint marks are particularly sought after by collectors, including the 1921 high relief, 1928-P, and the 1934-S. The 1921 issue was struck in high relief, making it distinctive from the rest of the series.
- **Condition:** As with most collectible coins, the value of a Peace Dollar varies greatly depending on its condition (grade), mint mark, and its year of production. Coins in uncirculated condition fetch higher prices, with high-grade examples from scarce years or mints being particularly valuable.
- **Special Notes:** The Peace Dollar was the last U.S. dollar coin struck for circulation in silver. Its historical significance, beautiful design, and the messages of hope and peace it carries make it a favorite among collectors.

The Peace Silver Dollar holds a unique place in American numismatics, celebrated not just for its aesthetic appeal and silver content, but also for the optimistic spirit it symbolizes in the aftermath of World War I. For collectors, the Peace Dollar series offers a range of collecting opportunities, from affordable circulated pieces to rare and valuable key dates.
