Editing Perfin (section)

==Collecting perfins==
Formerly considered damaged and not worth collecting, perforated postage stamps are now highly sought after by specialist collectors. It is often difficult to identify the originating uses of individual perfins because there are usually no identifying features; for instance the Kodak company used a simple K as their perfin, but on its own a stamp perforated K could have been used by several other users. A ''K'' perfin still affixed to a [[Cover (philately)|cover]] that has some company identifying feature, like the company name, address, or even a [[postmark]] or [[Cancellation (mail)|cancellation]] of a town where the company had offices, enhances such a perfin.  Note that the block of 12 stamps illustrated on the right includes two copies of the highly sought-after erroneous 5-cent denomination instead of 2 cents.<ref>"Scott Standard Postage Stamp Catalog" (Scott Publishing Co., Sidney, OH, published annually), Vol. 1.</ref>
