Editing Definitive stamp (section)

== Frequency of issue==
Since postal administrations know that many [[stamp collector]]s want to own every stamp of a definitive series, and a complete series can be quite expensive, there is always the temptation by governmental bureaucrats to make extra money by frequently issuing new definitive sets, as well as including stamps with very high face values in a set.  Collectors' organizations <!--need the names--> have recommended that administrations only bring out new definitive issues no more often than every five years, and most administrations of the world follow this policy.{{citation needed|date=December 2010}} An exception would be the death of a monarch, or other prominent leader, necessitating a new definitive series for the new ruler. Sometimes merely the portrait is changed, and the outer design (known as the frame) remains the same throughout several issues. Countries that ignore frequency of issue guidelines and issue volumes of stamps that have little to no practical usage produce what many collectors refer to as ''wallpaper''.
