Collectible coins can include a variety of types such as commemorative coins, bullion coins, and currency coins. The 1972 San Francisco mint marked half dollars, particularly those in uncirculated or proof condition, are highly sought after by collectors. They feature the iconic design of John F. Kennedy on the obverse and the presidential seal on the reverse. A 50-cent roll of these half dollars typically contains 20 coins and can represent both a numismatic investment and a historic piece of American currency.
