Walking Liberty half dollar
The Walking Liberty half dollar is a silver 50-cent piece or half dollar coin that was issued by the United States Mint from 1916 to 1947; it was designed by Adolph A. Weinman, a well-known sculptor and engraver.
Oscar Roty's "Sower" design for French coins may have inspired Weinman's obverse.
Weinman's 1909 Union Soldiers and Sailors Monument may have given him his head of Liberty (from the head of Victory, on right) and displays similar use of foliage.

Half dollar (United States coin)
The half dollar, sometimes referred to as the half for short or 50-cent piece, is a United States coin worth 50 cents, or one half of a dollar. In both size and weight, it is the largest United States circulating coin currently produced, being 1.205 inches in diameter and 0.085 in (2.16 mm) in thickness, and is twice the weight of the quarter. The coin's design has undergone a number of changes throughout its history. Since 1964, the half dollar depicts the profile of President John F. Kennedy on the obverse and the seal of the president of the United States on the reverse.
