Obverse 1
The photo below shows the 1850-O Obverse 1 attribution grid. This is the only 1850-O obverse die,
so the date position is enough for attribution.

Obverse 1 Die States
- Perfect die.
- A faint die crack joins stars 7 and 8, passing through the head at eye level. A radial die crack extends from the rim to the
lower left tip of star 1, exiting the star at the upper right tip and passing through stars 2-3. The crack is very faint after
it exits star 1.
- Another radial die crack extends from the rim through the left side of the 0 in 1850 to the rock base.
No later die states have been observed.

Reverse A
The 1850-O Reverse A mintmark is high and slightly left of centered. The reverse also exhibits numerous light die lines and lumps.
Some of these are indicated by the arrows in the photo below.
