The right side of the 1 in the date is right of the shield point.
There are some die file marks just to the right of the shield, and a small die line about halfway down the space between the 2nd and 3rd stripes on the shield.
Later die states will show curved lines from when the die was re-polished for striking additional proofs (photo below).
Later state die polish lines
In still later die states, some minor cracks appear within the denticles below the date.
Date Position: M 3.5, 0.55 mm
There are two die markers on the reverse, located by the arrows below. See the two additional detailed close-up photos below.
One die line runs diagonal down and to the right, just left of the eagle’s tail feathers (photo below).
The other is a line underneath the eagle’s left (right facing) wing, to the right of its tail feathers (photo below). This line can be difficult to see in low-grade examples.
