Obverse 4 Reverse E
Obverse Diagnostic Point(s) Reverse Diagnostic Point(s)
Comments: The primary Obverse 4 diagnostic point is the die gouge to the left of Liberty's index finger. Tim Cook pointed out the possibility of using this die gouge as an attribution point around 1998. The date placement on Obverse 4 is very similar to Obverse 3, so the die gouge marker is very useful and recommended given the additional die states seen with this obverse die. Obverse 4 also exhibits a large die blob defect in the right field between Liberty's knee and Star 12.
Reverse E features a Medium O mintmark that is positioned right and high. Faint die cracks are just beginning to emerge on the plate coin. I have seen another earlier die state example with no reverse cracks. The obverse and reverse are well struck during this die state, unfortunately this does not last long.
