Ron Guth: The "Medium" Date 1848 Half Dime utilizes the normal Half Dime logotype for this year. Conversely, the "Large" Date was created when a Mint engraver inadvertently used a Dime logotype to punch the date into the die. There is a clear difference in the size of the two logotypes, with the large date overlapping the base of Liberty by an obvious margin.Of the two sizes, the Large Date is slightly scarcer than the Medium Date.
