Understanding Error Dimes
Error dimes result from mistakes during the minting process, leading to unique variations that deviate from standard coinage. These errors can include missing mint marks, double strikes, off-center impressions, or incorrect planchet usage. The rarity and distinctiveness of these errors significantly enhance the coin’s value among numismatists.
