肯尼迪半美元
There are three basic reverse designs. The first, for copper coins, features the value of the coin ("half cent" or "one cent") surrounded by a wreath or vine. The words "UNITED STATES OF AMERICA" encircle the wreath. In 1795-1797, a scrawny, naturalistic bald eagle was depicted on the reverse side of all silver coins. This design is known as Draped Bust, Small Eagle and usually commands a high price due to the extremely low mintage at the time. In 1798, the small eagle was replaced by the Heraldic eagle. This design is known as Draped Bust, Heraldic Eagle. The famous 1804 silver dollar has this design as well the reverse of the Kennedy half dollar in 1964. Three denominations also bore the appropriate fraction: half cent (1/200), large cent (1/100) and half dollar (1/2).
