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 four leaves beneath the "E" in "States" as used on 1855 patterns. This reverse was also used on J167-J171/P193-P197. To see all 3 reverses side by side, click here. These were struck in copper or bronze and is much rarer than the J163/189. Judd says that these are restrikes. This image is a composite. Photos used courtesy of PCGS.
