Dummy and Test stamps
From time to time, the post office has ordered test stamps of various
types. These are non-denominated stamps with no monetary value that
can be used in training exercises and to familiarize postal service
personnel with new formats.
Some of the dummy and test issues have been issued with plate numbers.
