 Mint Chief Engraver Frank Gasparro made minor changes to all three reverse designs. Gasparro simplified the quarter design, altered the drum for the sake of authenticity, changed the lettering and modified the expression on the drummer's face. He made slight changes to Independence Hall on the half dollar and altered the shape of the Liberty Bell and of the lettering on the dollar, simplifying the features visible on the moon. Ahr later stated that he would have liked more time to finalize his design, wishing to clarify the features of the drummer's face. The initials of the designer were added to the design by the Mint. All three agreed that Gasparro's changes improved their designs.
