Roosevelt dimes have been struck continuously since 1946, producing a long run of collectible varieties and mint errors. Dimes are small enough that errors can be subtle and easy to miss, but they are large enough to show clear detail under magnification. Their clad composition since 1965 means pre-1965 silver dimes with errors can carry extra premiums.
Dime errors cover manufacturing defects on Roosevelt dimes (1946-present) and earlier Mercury dimes (1916-1945). The transition from silver to clad composition in 1965 created additional error possibilities including transitional composition errors.
Dime errors are generally scarcer than penny errors because dimes receive more quality control at the mint. This scarcity can translate to higher premiums for comparable error types. Condition and the specific variety are major value drivers.
