The Half Eagle is a United States coin that was produced for circulation from 1795 to 1929 and in commemorative and bullion coins since the 1980s. Composed almost entirely of gold, it has a face value of five dollars. Its production was authorized by The Act of April 2, 1792, and it was the first gold coin minted by the United States.
In 1908, the final type, designed by Bela Lyon Pratt, was first produced. The composition, weight, and diameter of the half eagle coin remained unchanged, but both the obverse and reverse were drastically altered. The new design matched the new quarter eagle design of the same date. These two series are unique in United States coinage because the design and inscriptions are stamped in incuse, rather than being raised from the surface, meaning that the flat surfaces are the highest points of the coin. The obverse depicted an Indian head wearing a feathered headdress. The reverse depicted a perched eagle with the inscriptions “E PLURIBUS UNUM” and “IN GOD WE TRUST”. Production of the half eagle was suspended during World War I and not resumed until 1929, the final year of issue.
