 Longacre was recognized in an exhibit of 100 notable American engravers sponsored by the New York Public Library in 1928 . In 1970 , art historian Cornelius Vermeule , in his volume on U.S. coins , viewed Longacre and his works less favorably , " uniform in their dullness , lack of inspiration , and even quaintness , Longacre 's contributions to patterns and regular coinage were a decided step backwards from the art of [ Thomas ] Sully , [ Titian ] Peale , [ Robert ] Hughes , and Gobrecht " and " whatever his previous qualities as an engraver of portraits , he seems not to have brought much imagination to his important post at the Philadelphia Mint . " However , Vermeule considered the Flying Eagle cent more of a work of art , far above the mundane .
