1915-S Panama-Pacific Exposition Quarter Eagle. MS-65 (PCGS). CAC. Here is an appealing CAC-approved Gem example of this scarce and conditionally challenging issue in the United States Mints classic commemorative series. Intense and satiny mint luster blends with vivid lemon-yellow coloration. The eye appeal strong and the surfaces are as smooth as would be expected for the assigned grade. Among the finer survivors from a net mintage of just 6,749 coins, initially priced at $4. Charles E. Barber and George T. Morgan combined their efforts to create the designs.
