 Once Beach accepted the commission on March 12 , 1928 , Juliette Fraser 's sketches were forwarded to him . On April 7 , he sent completed models to the Mint and photographs to the Fine Arts Commission . Both the Mint and Houston responded with criticism , the former that the relief of the coin was high and difficult to reduce to coin @-@ sized hubs . On April 19 , Mint Chief Engraver John R. Sinnock wrote in a memorandum that the coin would be very hard to produce because the area of greatest relief on each side was in the same part of the design . Beach agreed to lower any high points that might cause the Mint difficulty .
