1915-s Panama Pacific Old Commem Half Dollar 50c Grades Choice AU/BU Slider BY SEGS. The 1915 Panama Pacific Half Dollar represented only the second commemorative silver half dollar issued by the United States Mint. Although this would later become the most frequent denomination for classic commemorative coins, the earlier issues took place across a range of denominations. The program of five commemorative coins issued for the Panama Pacific International Exposition included two versions of a $50 gold piece, a gold quarter eagle, and a gold dollar.The half dollar featured the full length figure of the allegorical Columbia with rays of the sun and the Golden Gate in the background. Her arms are outstretched to scatter fruits and flowers. A cherub appears to her right holding a cornucopia. The obverse includes the “S” mint mark, as the coins were produced at the San Francisco Mint facility.The reverse of the Panama Pacific Exposition Half Dollar features an American Eagle with wings outstretched, perched on a shield. An oak branch and olive branch appears to each side to represent strength and peace. The words “In God We Trust” appear near the eagle’s head, representing the motto’s first appearance on a commemorative coin. The obverse of the coin was designed by Charles E. Barber, and the reverse was designed by George T. Morgan.When Examining the Pan Pac Half Dollar, Note that there is a Problem with Pan-Pac Halves in its Strike: Weakness is often Evident on Columbia’s Head, Cap, Arm and Body, also on the Eagle's Breast Feathers and Claws. Occasionally, Coins are seen with a Rim Indentation Near the Periphery on Each Side; this is a Mint Caused Problem and Should Not Be Factored Into the Grade. When Grading Lightly Circulated Examples, Friction is First Evident on Columbia's Shoulder and on the Eagle's Breast.
