 A number of blunders can be seen among the early coins produced at the Mint under Longacre , though it is uncertain to whom these errors should be attributed . These include the 1844 half dollar struck at the New Orleans Mint ( 1844 @-@ O ) with a doubled date , and the 1846 half dollar with the 6 overlying an identical digit , but one which had been placed horizontally . Bowers indicates that Longacre likely delegated such work , although in 1849 he wrote that his daily work was punching dates into working dies . Tom DeLorey , in his 2003 article on Longacre , notes that Peale and his staff often made punches without consulting the Engraver 's Department ( headed by Longacre ) , and believes the chief coiner more likely to be responsible .
