Collectible coins, particularly in the context of the United States, often include various denominations and special issues. Half dollars, such as those minted in 2000 at the San Francisco Mint, are notable examples, especially when they feature unique designs or low mintage figures. The 50 cent roll can contain both standard circulation coins and collectible proofs that appeal to numismatists. Collectible coins are valued based on factors such as rarity, condition, and market demand, making them sought after by collectors and investors alike.
