The model for the Indian design is where fact and legend mingle. Obviously a white female and not a Native American, the profile has been attributed to both Longacre's daughter Sarah and the Greco-Roman statue Venus Accroupie ("Crouching Venus"). The facial features have many similarities to that used on Longacre's 1854 $3 gold coin, and to a lesser extent his previous gold designs. And this identical profile recurs, with many different headdresses, in Longacre's sketchbooks from ten years earlier. Though Longacre never disclosed the source of his inspiration in his writings, one of his early drawings of Sarah does bear a striking resemblance.
