What is canal zone stamps?

The Canal Zone was a geopolitical zone that existed from 1903 to 1979 in which the Panama Canal was located. During this time, stamps were issued by the Canal Zone postal service. The first stamps were issued in 1904 and featured the Canal Zone's seal. Over the years, various designs were used, including depictions of the Panama Canal and important figures in Canal Zone history, such as Theodore Roosevelt and William Gorgas. Most Canal Zone stamps were printed in the United States, although some were printed in other countries, such as Panama and Switzerland. After the Canal Zone ceased to exist as a separate entity in 1979, collectors continued to pursue Canal Zone stamps as part of their interest in the history and culture of the region. Today, Canal Zone stamps are considered valuable and collectible items, particularly those featuring rare designs or errors.
