Longacre's flying eagle design. This was apparently copied from Christian Gobrecht's dollar and half dollar patterns in the late 1830s.
This obverse was combined with 3 different reverse designs.
On this one, there are three leaves beneath the "E" in "States". Unlike the other 2 reverses, this was only used on this design. As the central portion of the illustrated piece appears weak, it was likely rejected.
Examples are known as follows:
Copper J165A/P191 with at least 3 known.
Bronze J165B/P191 with at least 3 known.
