Collectible coins, such as the Kennedy Half Dollar, are often sought after by numismatists for their historical significance and unique designs. The Kennedy Half Dollar, introduced in 1964 to honor President John F. Kennedy, features the presidential bust on the obverse and the presidential coat of arms on the reverse. The 2010 Kennedy Half Dollar was minted primarily for collectors, as it was not released for general circulation in large quantities. Collectible coins are typically graded based on condition, rarity, and demand, impacting their market value.
