Commemorative stamp (from French comme - like memoria - memory) is a general name for special artistic (commemorative, commemorative and other) postage stamps, which are often issued on a significant date, for example, an anniversary, for veneration or a place of celebration, event, person or object.
The term "commemorative stamp" means, in addition to those mentioned above, also thematic stamps (pictures on which are dedicated to a specific collectible topic).
Sometimes this term is used to simplify the terminology, for example, in cases when it is only necessary to emphasize that the stamp is not in common use (that is, the standard, which is issued by postal administrations for everyday mass consumption and is used without limitation of circulation).
Many postal services issue several commemorative or commemorative stamps each year, sometimes spending the first day of the issuance ceremony at locations related to items. Commemorative seals can be used alongside regular stamps. Unlike standard postage stamps, which are often reissued and sold over a long period of time for general use, commemorative stamps tend to be printed in limited quantities and sold for a much shorter period of time, usually before delivery ends.
Thus, commemorative stamps are produced, as a rule, in a relatively small circulation by a certain date at a high printing level, in contrast to standard postage stamps, which have been valid for many years, are printed in mass circulation and sometimes have additional runs.
