From Stamps of the World
A definitive stamp is a postage stamp that is part of the regular issue of a country's stamps, available for sale by the post office for an EXTENDED period of time (Wikipedia). A regular stamp is thus not ipso facto definitive. The first non-definitive, Commemorative stamps were issued in the end of the 19th century: Peru in 1871, New South Wales in 1888 (considered the first issue with explicit mention of a Commemorative issue).
