The medal's obverse bears bust of William Penn, facing quarter-right. Around, 1682 · ARRIVAL OF WILLIAM PENN IN AMERICA · 1932; to left and right, AETIS. 22. - 1666.; signed over shoulder at right, Kilenyi; SAMPLE stamped across figure.
The medal's reverse bears scene of William Penn shaking hands with Native American leader, tribal council seated around, forest in back.
The circular medal was struck in bronze and sterling silver by the Whitehead-Hoag Company of Newark, New Jersey. While quite common as a "So-called Dollar" with a diameter of 38.1mm in bronze, the silver variant is much less common and the large bronze medal has a reported mintage of only 250 pieces.
The small "So-called Dollar" variants have the numbers 461 and 462 in the Hibler & Kappen catalog of "So-called Dollars."
Many thanks to Harry Waterson for the information on mintages.
