Struck in 90% fine silver at the Denver Mint, the 1939-D Liberty Walking half dollar circulated throughout the central and Rocky Mountain regions of the country. These areas were gaining population rapidly in pre-World War II America, as people sought the "wide open spaces" no longer available in the eastern regions. Liberty Walking halves were popular coins bearing an artistically pleasing design. The 1939-D half dollar will be a handsome addition to your collection!
