These new pennies appear to have, on the reverse, a rejected design for Captain America's shield. And apparently before that there were Lincoln bicentennial designs, which were also bad, if fortunately short-lived.
What was wrong with the Lincoln Memorial? What could possibly have been wrong with the Lincoln Memorial? It is a handsome building. Lincoln was on the right side both of his time and of history.
Apparently this shield is meant to represent the unity that was President Lincoln's legacy to his grateful country. Sure. To me, it represents both bad art and laziness. Which is similar, I guess.
