On January 7, 1913, Fraser's approved design was used to strike experimental pieces; the sculptor later wrote that he remembered several of the workmen commenting that the new piece struck more easily than the old. Afterwards, Roberts asked Fraser if the Hobbs Company was content with the design. The sculptor told the Mint director that the firm wanted changes made, and Fraser agreed to meet with them further. Over the following two weeks, Fraser worked with George Reith, the Hobbs Company's mechanic who had invented the anti-slug device, in an attempt to satisfy the firm's concerns. On January 20, Fraser wired the Mint from his studio in New York, announcing that he was submitting a modified design, and explained that the delay was "caused by working with inventor until he was satisfied". The next day, Philadelphia Mint Superintendent John Landis sent Roberts a sample striking of the revised design, stating, "the only change is in the border, which has been made round and true".
