Collectible coins, specifically the 1925 Peace Dollar minted in San Francisco, are notable examples of U.S. numismatic history. The Peace Dollar series was produced from 1921 to 1935, celebrating the end of World War I and symbolizing peace. The 1925 San Francisco mint issue is particularly sought after due to its lower mintage and the quality of its design, featuring Liberty on the obverse and an eagle on the reverse. As a result, it often commands premium prices among collectors.
