1876-CC Trade Diollars are found in the following combinations:
Obverse 1, Reverse 1 Obverse 1, Reverse 2
Here's how to tell them apart:
Obverse 1 has three fingers on Liberty's outstretched hand (Obverse 2 has four fingers, but it has yet to be identified on any 1876-CC Trade Dollars) Reverse 1 has a berry under the eagle's left talon (viewer's right) Reverse 2 has no berry
