This commemorative stamp series was issued to publicize the upcoming 1915 Panama-Pacific Exposition that was held in San Francisco. The exposition commemorated the discovery of the Pacific Ocean as well as the construction of the Panama Canal.
The stamps were initially issued in 1913 (#397-400A) and were popular with the public. They pictured Vasco Nunez de Balboa, who discovered the Pacific Ocean in 1513, the Panama Canal, the Golden Gate, and the discovery of San Francisco Bay. However, it wasn’t long before the Post Office Department began hearing complaints that the stamps came apart too easily along the perforations.
In an effort to make the stamps stronger, perforating machines were altered from 12 perforations per two centimeters to 10 perforations per two centimeters in 1914-15. The Panama-Pacific commemoratives were among the first stamps to be reissued with the higher-gauge perforations.
This is your chance to own all four 1914-15 Panama-Pacific Exposition stamps in one convenient order. You’ll save time and money.
