Collectible coins, such as dimes, can vary significantly in value based on factors like date, mint mark, and condition. The 1987 Denver minted dime is part of a series of dimes produced in the United States, often sought after by collectors for its design and historical significance. A roll of 10c dimes contains 50 coins, totaling $5.00 in face value, but the collectible aspect may increase its market worth depending on rarity and demand among numismatists.
