The American Innovations Dollar Collection is beautiful and educational, containing the Philadelphia and Denver minted dollar coins honoring this new program of American ingenuity. Both coins sit within a Lock-tite, crystal clear enclosure affixed to a full color 5x15 inch tri-fold containing information about the United States Patent process and highlighting some of America's greatest inventors.
The United States Mint American Innovation $1 Coin Program is a multi-year series honoring innovation and innovators with $1 coins from each State, District of Columbia, Puerto Rico, Guam, American Samoa, U.S. Virgin Islands, and Northern Mariana Islands. The Pennsylvania coin is the second of four to be released this year. It features the polio vaccine developed by Dr. Jonas Salk and his team at the University of Pittsburgh in the early 1950s. At the time, polio was a devastating disease that disproportionally affected children and young adults and left many paralyzed and unable to walk.
The reverse depicts an artist’s conception of the poliovirus at three different levels of magnification along with the silhouette of a period microscope, representing the extensive research conducted to develop a cure for polio. The inscriptions are “UNITED STATES OF AMERICA,” “POLIO VACCINE,” “1953,” and “PENNSYLVANIA.”
The obverse design features a dramatic representation of the Statue of Liberty in profile with the inscriptions “IN GOD WE TRUST” and “$1.” The obverse also includes a privy mark of a stylized gear, representing industry and innovation.
The edge-incused inscriptions are “2019,” mint mark, and “E PLURIBUS UNUM.”
