Collectible coins encompass a wide range of numismatic items, appealing to both investors and hobbyists. In the United States, half dollars, particularly those minted at the San Francisco Mint, such as the 1998 issues, are sought after for their unique designs and limited availability. A 50c roll refers to a standard roll containing 20 half-dollar coins, totaling $10 in face value. San Francisco mintages often possess distinct characteristics, including proof or special releases, enhancing their collectible value.
