The U.S. Mint has redesigned the back of the Lincoln one-cent penny. Gone: the Lincoln Memorial. New: some shield. Oh, wait, here's what the U.S. Treasury says: "The 13 vertical stripes of the shield represent the states joined in union to support the federal government, represented by the horizontal bar above. The union shield, which dates back to the 1780s, was used widely during the Civil War. It is also featured on frescoes throughout the halls of the U.S. Capitol, completed in the mid-19th century..."
God, I lost interest after "13 stripes"... And of course, it's still just a penny. Two-hundred of 'em will buy you a cup of coffee.
