GROUP TST: Stamps generated in equipment and component tests
- Most of the stamps in this group were listed as Specimens (Sub-group B) in earlier editions of this catalog. Specimens are primarily generated for publicity and promotional purposes and are meant for public release. Test stamps have a different purpose. They are used by meter companies to preview town marks and slogans before release to the customer. Such test stamps are typically destroyed after use.
- Test stamps are also generated when variable rate stamp vending machines and digital post office franking systems are switched on. Such stamps indicate if everything has initialized properly. Test stamps such as this occasionally are found in trash bins near the machines.
