3. Reverse Features:
- The reverse (back) of the coin features an eagle with outstretched wings, clutching an olive branch and arrows. The words "UNITED STATES OF AMERICA" are inscribed around the rim, along with the denomination "ONE DOLLAR." Genuine Trade dollars have distinct feather and wing details on the eagle.
