Editing Cancelled-to-order (section)

==Misuse of cancellations==
An illegitimate practice related to CTOs involves deliberate misuse of cancellation devices to make a stamp appear used. This typically happens for stamps from remote places, or that were in use for only short periods. Used stamps can be more valuable than unused, sometimes by an order of magnitude. This form of [[philatelic forgery]] may involve use of rare types of canceling devices, unusual dates in [[postmark]]s, and so forth.
