Collectible coins, specifically half dollars from the United States, are a popular category among numismatists. The 2011 half dollars, which are part of the standard Mint releases, include designs such as the Kennedy half dollar, introduced in 1964. A 50-cent roll typically contains 20 coins, totaling $10 in face value. These coins may appeal to collectors for their historical significance, design, or potential for appreciation in value.
