Collectible coins can include a variety of types such as commemorative issues, proof coins, and semi-numismatic collectibles. In the United States, half dollar coins, specifically the 50-cent pieces, often appeal to collectors for their unique designs and historical significance. The 2004 San Francisco mint releases feature distinctive qualities, such as a mirror-like finish in the proof versions, making them desirable among numismatists. Collectors often seek out rolls of these coins for both their aesthetic value and potential investment return.
