Suspect Scott #390, Used Single (2/15/16).
This stamp was part of a larger collection of larger collection of Washington/Franklins I bought at auction in January of 2014. From the Experts Book – “Ordinary pairs of this coil are rarely faked. It is an inexpensive coil and the imperforate stock from which it can be made costs about the same. Guideline pairs, however, are often faked, because the unused value multiplier is about 4x.” This coil can be made by adding perforations at the top and bottom of a trimmed #383 or adding perforations at the top and bottom of a #383V imperforate coil.
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.
The suspect has a single line watermark “U” at the top, it is impossible to determine if the orientation is normal or reversed.
The width of the suspect is just over 21.25mm at the top and just under 21.5mm at the bottom.
The suspect perforations match known genuine gauge 8 ½ perforations.
The perforations have all the signs of being genuine - slightly oval in shape, pulled paper fibers on the left side of the hole and there is a pressure ridges visible on most of the perforations when viewed at low magnification and angled lighting.
Conclusion: In my opinion the perforations are genuine therefore the suspect is a genuine Used Scott #390, creased.
