1870 $5 (1870 Half Eagle) NGC AU50. The strong obverse strike and pleasing surfaces for the grade make this 1870 Half Eagle very appealing. Attractive, subdued mint luster is seen within its devices. The diagnostics for the grade assigned are present. These include the separation of the curls above the eye and down the neck, and the hair on top of the head. The Liberty Head (Motto on Reverse) half eagle was minted from 1866 to 1908.

It was designed by Christian Gobrecht and showed Liberty wearing a coronet as she faced left in profile. Her hair is tied in the back with beads while two loose curls flow down her neck. She is surrounded by thirteen six-pointed stars with the date below. Dentils are near the edge of both sides of the coin. The reverse of the coin shows the heraldic eagle with its head turned to the left. In its talons it holds an olive branch and arrows, symbols of peace and preparedness. Above its head on a banner, the motto IN GOD WE TRUST was added. The denomination is below. In addition to dentils, it has a reeded edge.

In March, 1865, a coinage act was passed that required that the motto be added to all coins large enough to accommodate it. The Mint interpreted this to mean for gold coinage the half eagle, the eagle, and the double eagle. The Liberty Head (Motto on Reverse) half eagle was created as a result of this mandate. (All silver coins larger than a dime also had the motto added.)

According to the records of the United States Treasury Department, the first request for the recognition of God on coinage was made in a letter from the Reverend Mark Richards Watkinson of Ridlelyville, Pennsylvania on November 13, 1861 to Salmon P. Chase, Treasury Secretary.
