I would go with the newest information out there which is that by Osburn and Cushing.
http://www.seateddollarvarieties.co...45-OC1.shtml
They list three die states for the obverse:
State a: Perfect die
State b: A single light clash mark is visible in the field under the arm
State c: Double clashing under the right arm, with rather wide separation
They list two die states for the reverse:
State a: Perfect die
State b: Faint clashing visible as a light line connecting the upper leaf to the left wing
This information came from thee link above which is the digital version of their recently printed book.
