Suspect Scott #349, Used Single.


Update: The A.P.S. has certified this suspect as a genuine #349.

This is a reasonably priced issue cataloguing for $100 as a used single. This coil is often faked and can be manufactured from the following stock: adding fake perforations to a trimmed imperforate #344, adding fake perforations to the imperforate vertical coil #344V, trimming the perforations off the left and/or right of a perforated #332 and trimming the perforations from the left or right of the #332a booklet stamps.

The watermark is a double line “S” and “P”, normal that reads horizontal. The horizontal watermark eliminates the possibility of the suspect being a #332a booklet single.

The width of the suspect is 21.5mm (-) at the bottom and 21.5mm at the top which is close to the ideal 21.5mm and the two cut edges are parallel.

The top perforations gauge out to 11.90 and slope down slightly from left to right, the bottom perfs gauge at 11.97 and are parallel to the frame.

The images below show the suspects perforation overlaid on genuine perforations.


On closer examination the perforations do show the signs of being genuine – slightly out of round, pulled paper fibers on the right edge of the perforations, no pressure ridges can be seen though. The second and third perf tips from the left on the top have been pulled out by their roots.

I compared the left and right edges of the suspect with the edges on a #348 paste-up single and they match rather well.


Conclusion: In my opinion the suspect is a genuine #349, there are two pulled perfs at the top. I’ll be sending this stamp out to the APS to be checked out.
