U.S. dimes produced before 1964 were composed of a significant quantity of silver and are worth, at a minimum, their weight at the going price of silver. Typically, these silver dimes are approximately 0.07 ounces and worth well over a dollar.
The earliest U.S. silver dime was the Bust dime, which was made between 1796 and 1837. As of 2015, these coins have a minimum value of $35 due to their relative rarity; coins in uncirculated condition are worth up to $3,310. Seated dimes, which were produced between 1837 and 1891, have a value range between $10 and $120 depending on condition. Barber dimes, circulated between 1892 and 1916, are typically worth from $2 to $65, while Mercury dimes used between 1916 and 1945 are worth significantly less. The final silver dime issued, the Roosevelt dime, was used between 1946 and 1964 and is worth approximately its weight in silver, even in uncirculated condition.
