In 1915, the Panama Pacific exposition opened in San Francisco as a celebration of the finishing of the Panama Canal. San Francisco also used the opportunity to show the world the city’s resilience and ability to rebuild after the devastating earthquake and fire of 1906. The 636 acres of this 1915 world’s fair drew nearly 19 million visitors over its nine-month residency. Among other attractions, the Panama Pacific Exposition was the first world’s fair to demonstrate a transcontinental telephone call. Could this 1915 half eagle have been carried across the country to visit the San Francisco world’s fair?
