The "early dime" refers to the fact that the 1891 dimes were minted with a slightly different design than the later dimes of that year. The early dimes have a smaller "S" mintmark on the reverse, while the later dimes have a larger "S" mintmark. The early dimes are generally considered to be more valuable than the later dimes, especially in higher grades.
