The Mercury Dime is possibly the most popular series when it comes to dimes. First struck in 1916 until the end of WWII in 1945. Collecting the earlier dates of Mercury Dimes is very difficult when looking for uncirculated condition. Especially looking for the 1916-D and both the Philadelphia and Denver issues of the 1921 Mercury Dime. Our 1941-1945 is a notable short set to collect as it coincides with the WWII dates from when America entered.
