Collectible coins refer to numismatic items sought after by collectors for their historical significance, rarity, or intrinsic value. In the United States, half dollars, specifically the 50-cent coins, include various designs and mint marks that can affect their value. The 1973 Half Dollar, minted in San Francisco, is a notable example, featuring the iconic Kennedy design. Rolls, such as a 50c roll, typically contain 20 coins, making them an attractive option for collectors looking to acquire multiple pieces from a specific year or mint.
