The American Innovation gear privy mark appears at the lower left, flanked by the engraver's initials JK below and PH to the right of the effigy. |

| Reverse description | The reverse depicts a bold symbolic composition commemorating Jonas Salk's development of the polio vaccine at the University of Pittsburgh in Pennsylvania. At the left, a stylized laboratory microscope is shown in outline relief, while the center-right field is dominated by a large icosahedral representation of the poliovirus particle rendered in faceted geometric detail. Surrounding the virus particle is a backdrop of hexagonal molecular lattice patterns extending across the upper and right portions of the field. The inscriptions POLIO VACCINE and 1953 appear in two lines within the central field, with UNITED STATES OF AMERICA arranged along the left border and PENNSYLVANIA along the lower border. The engraver's initials RMM appear at lower left and JFM at lower right. |

Pennsylvania's innovation honoree for this series was the Slinky — invented by naval engineer Richard James in 1943 after he accidentally knocked a tension spring off a shelf and watched it walk across the floor. The toy went on to sell 300 million units. Whether that qualifies as the defining innovation of a state that also produced the first computer (ENIAC) and the nation's first oil well is a question the selection committee apparently resolved without much public debate.
