 On March 4 , 1909 , the day on which Roosevelt left office , replaced by William Howard Taft , Brenner met with Mint Engraver Charles E. Barber in Philadelphia . Barber had written to Leach , suggesting that Brenner 's designs would have to be modified to be suitable for coinage . On March 15 , Brenner wrote to Leach stating that Barber seemed in no hurry to have the new coins produced . Brenner also complained that the Mint was losing detail as it reduced the large models to coin @-@ sized hubs . Barber had been stung by criticism that he had lost detail in this way with the new gold coins , and he raised no objection to having the reductions done by an outside silversmith . After several hubs were prepared by the Medallic Art Company of New York , Barber sank a master die and sent it to Brenner for retouching .
