Comments: The Obverse 4 die gouge is very visible on this EF plate coin. A die defect on Liberty's nose has appeared during this later die state. Obverse 4 is paired with a badly lapped reverse die that I have designated as Reverse F. This reverse die exhibits a Medium O that is centered in both horizontal and vertical planes. Both the mintmark and design elements are very weak. Until November 2006, no other die pairings with 1842-O Reverse F were known. However, the author recently located an 1841-O Medium O dime that has been struck from this Reverse F die. When employed in 1841, this reverse die exhibits more device element details suggesting a lapping between usage with the 1841 Obverse 2 die and the 1842 Obverse 4 die.

Additional research is required to locate a dime with an early die state of Reverse F. Who knows what dated obverse die will be paired with an early die state specimen?
