 In the mid @-@ 1850s , Longacre was engaged by the Navy Department to design a medal to be presented to Captain Duncan Ingraham . Longacre produced the imagery used for the reverse ; the obverse was by Assistant Engraver Cross . Although Bowers describes Longacre as having been " strictly ethical in the duties of his office " , when the Treasury Department learned that Longacre accepted a $ 2 @,@ 200 payment from the Navy for his work , they required that he repay the money under a federal law barring compensation of this kind . Other than his design for the 1867 Assay Commission medal , and his similar , wreathed reverses for the commission medals in 1860 , 1861 , and 1868 , the Ingraham work was Longacre 's only medal made for the government .
