The value of a 1908 dime depends on its condition and rarity. In general, a 1908 dime in good condition is worth around $1. However, a 1908-S dime, which was minted in San Francisco, can be worth up to $20 in good condition. A 1908-D dime, which was minted in Denver, can be worth up to $15 in good condition. The value of a 1908 dime can also be affected by its grade, which is determined by a professional coin grading service. A 1908 dime that is graded MS-65 or higher can be worth significantly more than a 1908 dime that is graded MS-64 or lower.
