U.S. Possessions

This section illustrates plate number material for Canal Zone issues that are not overprints of regular U.S. stamps.

Canal Zone (1904-1938, 1939-1978)

Stamps of the Canal Zone superseded the overprinted U.S. issues in 1938. Stamps of Panama were used during the 1979-1999 transition period. In 1999, ownership of the Canal Zone and operation of the canal reverted to Panama.

Early issues

CZ Scott 39d, "Canal Zone" reading down, foreign order number 4068

Since there were no plate numbers on these stamps of Panama, the foreign order number is sometimes collected as the next best option.

CZ Scott 46, foreign order number 8848

These overprints were created when a 1920 order for 1¢ stamps from ABNCo in New York was delayed. When the Canal Zone post offices ran out, they purchased 200,000 1¢ stamps from Panama and had them overprinted. They were used from early March to mid April, 1921, when the stamps ordered from New York arrived. --from David Zemer, Canal Zone Philatelist, First Quarter 2021.

Airmail Official issues

The Gaillard Cut airmail stamps were overprinted for use as airmail official stamps. However, all selvage was removed from the panes as part of the overprinting process, thus no plate number varieties exist.
