 The engraving was unusually minute and required very close and incessant labor for several weeks . I made the original dies and hubs for making the working dies twice over , to secure their perfect adaptation to the coining machinery . I had a wish to execute this work single handed , that I might thus silently reply to those who had questioned my ability for the work . The result , I believe , was satisfactory .
