Your answer was: SAGGIO. |
Answer: From the first issue in 1929, Vatican City has produced examples of perforation and overprint Specimen (SAGGIO) stamps. Various specimen stamps are overprinted in black, blue or red ink in all capitals type font. It is not known how many were printed for each issue, but it is likely that no more than a few sheets each were printed. They are generally scarce to rare and are priced accordingly. Below are two examples of airmail specimens. A specimen stamp is a postage stamp sent to postmasters and postal administrations so that they are able to identify valid stamps and to avoid forgeries. Since 1879, members of the Universal Postal Union have supplied stamps to each other, and stamps supplied this way have frequently found their way on to the philatelic market. Specimen stamps have no postal validity so postal administrations are free to distribute them as widely as they like. This can include stamp dealers, philatelic magazines, government bodies, embassies and as promotional items to philatelists.
