Collectible coins, particularly U.S. half dollars, are popular among numismatists. The 50-cent roll of half dollars from 2010 minted in Denver consists of coins that are circulated but can have collector value depending on their condition and rarity. The half dollar, typically made of a copper-nickel alloy in this series, features designs that may include the famous portrait of John F. Kennedy. Collectors seek out these coins for their historical significance, mint marks, and potential for appreciation in value over time.
