Mercury dimes, officially known as Winged Liberty Head Dimes, were minted in the United States from 1916 to 1945. These iconic coins are a favorite among collectors, not just for their stunning design but also for their historical significance. Over time, some Mercury dimes have become incredibly rare and are now considered valuable collectibles.
