Collectible coins, particularly modern commemoratives, are coins issued by the United States Mint to honor significant events, individuals, or themes. The 50-cent coins, also known as half dollars, include various designs released to commemorate milestones. In 1991, the U.S. Mint produced commemorative half dollars, including those minted in Philadelphia, which feature distinctive designs celebrating American heritage and achievements. These coins are often sought after by collectors due to their limited mintage and thematic significance.
