Obverse 4 also features a tine extending from the top of the left end of the scroll, shown in the following photo. This tine is the result of a die crack. The crack occurred very early. I've seen very few examples of this obverse die without it, so it's a good marker to look for, but not conclusive.

Obverse 4 Die States

Perfect die (rare).
A short die crack crosses the ribbon, creating a tine that's visible on almost all examples.
Numerous light die cracks - Crossing the base of the date; from the ball of the 6 through the top of 0 into the rock to the sandal; joining the stars on the left.
The die has been polished. The details are weaker, and the date is very weak. The die cracks are still visible.

No later die states have been observed. OC-8 is found with all four obverse die states.

Reverse D
The photo below shows the mintmark position for Reverse D.

1860-O Reverse D mintmark

Reverse D displays no notable markers other than the mintmark position. This mintmark position is unique, highest of any for the year and centered very slightly left of directly under the intersection of the branch and feather tip.

Reverse D Die States

Perfect die.
Perfect die, but weakly struck around the NE in ONE, either from a clogged die or from heavy die polishing.

No later die states have been observed. OC-8 is found only with reverse die state b.
