The following casting was the subject of a recent article in the June 14, 2004 edition of Coin World by Paul Gilkes. According to uspatterns.com member Roger Burdette, who is doing extensive research on early 20th century patterns, this casting or galvano was prepared circa July 1916 by Herman MacNeil.
It was found along with a reverse casting by an anonymous collector at a garage sale. It is believed struck in bronze and is possibly nickel plated.
Differences between this and the other model which appears in Cline's Standing Liberty Quarter book include the motto "In God We Trust" on the ribbon and no olive branch in Liberty's hand.
Additional information can be found in Stacks 5/08 and Stacks-Bowers 11/12 sales.
