In an attempt to conserve copper for the war effort, the U.S. Mint in 1943 released a steel penny coated in zinc. These "steelies," however, were available for only one year (as the zinc faded and wore off over time). This commemorative coin collection, a great addition to any World War II-era showcase, includes ten such pennies, each one plated in 24-karat gold! Arrives with a story card and certificate of authenticity.
