Suspect Scott #412 Used Single.

This stamp was part of a larger collection of larger collection of Washington/Franklins I bought at auction in January of 2014. This is not an overly expensive stamp - $25 catalog value and is often faked. This stamp can be made by adding perforations to a #408 and trimming the top and bottom. Tthere is no perforated stock in which to make a #413 from. The fact that the only way to make this stamp is to add perforations to an imperforated stamp, an easy conclusion is that if the perforations can be determined to be genuine then the stamp itself is genuine. Below is an image of the suspect's perforations overlaid on a certified genuine #411 pair.

As can be seen from the above images the suspectís perforations match perfectly with the reference example. A close examination of the perforations under magnification show slightly oval shapes, pulled paper fibers at the top of the perf hole and hints of pressure ridges at the bottom of the perf hole

Conclusion: In my opinion the suspect is a genuine #412. The missing perfs on the left and the clipped perfs at the right were probably caused by a misaligned stamp affixing machine
