1915-S Pan-Pac $2.50 (1915-S Panama-Pacific Exposition $2.50) PCGS MS63 CAC. Significant amounts of mint luster remain on this 1915-S Pan-Pac Quarter Eagle. A few scattered marks on both sides keep this coin from a higher mint state grade, which is confirmed by CAC. Some flatness is noted on the head of the hippocampus and on the eagles leg. The coin was issued as part of the commemoration of the Panama-Pacific International Exposition in San Francisco, which celebrated the opening of the Panama Canal in 1914.

The obverse, designed by Charles Barber, shows Columbia facing backwards riding sidesaddle on a hippocampus. This device symbolizes the use of the Canal to transport goods. Columbia holds a caduceus, which alludes to the triumph over malaria and yellow fever epidemics.

The reverse, designed by George T. Morgan, shows an eagle perched on a Roman legion standard, which suggests the need to keep the Canal open during the war. The mintmark is on the obverse far to the right of the date in the exergue.
