Suspect Scott #393 Used Single.
This stamp was part of a larger collection of larger collection of Washington/Franklins I bought at auction in January of 2014. The Experts Book says that this issue is often faked and can be made by adding perforations to the left and right edges of a trimmed imperforate #384 or adding perforations to the left and right edges of the imperforate horizontal coil #384H. There is no fully perforated gauge 8 ½ stock from which this coil can be made from so if the perforations prove to be genuine then the suspect is genuine.
Since there is no fully perforated sheet stock from which to trim the left and right sides it stands to reason that if the perforations are found to be genuine then the suspect must be genuine.
A search of the Philatelic Foundations certificate database returns 399 certs with one showing as a fake coil but the associated image shows what looks like a pair of #391 (vertical coil) and a second that has an opinion of not genuine.
The suspect is just under 24 ¾ mm tall and the watermark is a single line “U”.
The perforations on the right are whole and when examined show the signs of what genuine perforations should look like: slightly oval in shape, pulled fibers on one side of the hole and pressure ridges on the opposite side. The suspects perforations were overlaid on genuine gauge 8 ½ perfs and the match is near perfect.
Conclusion: in my opinion the suspect is a genuine #393, used with the right straight edge caused by a stamp affixing machine or by someone using a pair of scissors.
