Collectible coins, such as the 1958 dimes from Philadelphia, fall under a category known as numismatics. These coins are often sought after due to their historical significance, rarity, and condition. The 10-cent roll containing 1958 dimes specifically refers to a collection of ten-cent coins minted in Philadelphia during that year. The Philadelphia Mint is known for producing coins without a mint mark, distinguishing them from those produced at other U.S. mints. Collectors may focus on the overall mintage, coin condition, and variety when evaluating these specific dimes.
