Editing Cancellation (mail) (section)

==Types of cancellations==
* '''[[Socked on the nose|Bullseye cancellation]]''', also called "Socked on the nose" or SOTN, is a stamp collector's term for a cancellation, typically of circular design, centered on the postage stamp. Such cancellations are popular with some stamp collectors because of their neatness and the fact that the time, date, and location where the stamp was used may be readily seen. The prevalence of bulls-eye cancellations varies considerably by country and time period.
* '''[[Cancelled-to-order]]'''.  Cancelled-to-order stamps, also known as CTOs, are stamps that have been cancelled by a postal authority, but were never used to transmit mail. CTOs are created by postal authorities to sell the stamps cheaply to stamp collectors.  Many Eastern European countries and others sold great numbers of CTOs to collectors in the 1950s–1990s strictly for revenue.  CTOs often may be identified as the stamps still retain their original gum.  Some authorities use the same canceller for all CTOs, and apply it very neatly in the corner of four stamps at one time. In some instances, the "cancellations" are actually printed as part of the stamp itself.
* '''Deferential cancellation''' is a cancellation designed so as not to deface the image of the ruler or regent on the stamp.<ref>[http://www.askphil.org/b25d.htm Glossary of Stamp Collecting Terms] {{Webarchive|url=https://web.archive.org/web/20120412204318/http://127.0.0.1/ |date=2012-04-12 }}.</ref>

* A '''[[duplex cancel]]''' includes a postmark as well as the cancellation.<ref>{{cite web |url=http://glossary.usstamps.org/glossary5.html |title=Glossary of Terms for the Collector of United States Stamps |access-date=2009-05-07 |url-status=dead |archive-url=https://web.archive.org/web/20070913192456/http://glossary.usstamps.org/glossary5.html |archive-date=2007-09-13 }}</ref>
* '''[[Fancy cancels]]'''.  In the second half of the 19th century, many postmasters in the United States and Canada cut their own cancelers from [[Cork (material)|cork]] or wood in a great variety of designs such as stars, circles, flags, chickens, etc.  These are known as fancy cancels and have been heavily studied by philatelists and collectors.<ref name="scott2"/>  One of the most famous is the "kicking mule" used in the 1880s.<ref>Lee Henry Cornell, ''The tale of the kicking mule; a handbook dealing with the famous kicking mule cancellation used in several western towns in the "eighties"'' (Printcraft Shop, Wichita 1949).</ref>
* '''[[First day of issue]]''' are special cancellations with the date the stamp is first issued for sale and include the words "First day of issue."
* '''Flag cancellations''' are a type of machine cancellation incorporating  a design of the United States flag with the stripes serving as the "killer".  The first machine flag cancel (preceded by fancy cancels of flags) was used in Boston in November–December 1894.<ref name="scott2"/>
* '''Handstamped cancellations''' are cancellations added by means of a hand stamping device.
* '''Highway post office cancels''' refers to cancels added in transit by portable mail-handling equipment for sorting mail in trucks.<ref name="linns.com">{{cite web|url=https://www.linns.com/insights/glossary-of-philatelic-terms.html|title=Glossary of Stamp-Collecting Terms For New Collectors - Linns.com|website=Linn's Stamp News}}</ref>
* '''[[Machine postmark|Machine cancellations]]''' are automatically added by machines that rapidly process large numbers of envelopes.  A 1903 silent film of an operating cancelling machine may be seen [http://memory.loc.gov/mbrs/awal/0870.mpg here].
* '''Mute cancel''' refers to a cancellation that includes no writing and thus "does not speak."
* '''Numeral cancels''' are cancels whereby number were used to identify specific post offices. For the [[United Kingdom of Great Britain and Ireland]], which started using numerals in 1844, the shape of bars indicate the actual country of use. Numerals were also used in combination with a datestamp in duplex cancellations.
* '''[[Pen cancel]]s''' refer to the use of a writing [[pen]] to deface the stamp, and were more common in the 19th and early 20th centuries.
* '''Pictorial cancellations''' include images associated with the commemoration of some event or anniversary.  Some people attempt to use stamps relating to the theme of a pictorial cancellation on the envelope.<ref>{{cite web|url=http://www.mcgees.org/postalcancel/postalcancelintro.shtml|title=Postal Cancel Art|website=www.mcgees.org|access-date=2002-09-01|archive-url=https://web.archive.org/web/20021014021548/http://www.mcgees.org/postalcancel/postalcancelintro.shtml|archive-date=2002-10-14|url-status=dead}}</ref>  See further below.
