Suspect Scott #388, Used Single (8/8/15).

This is a very expensive stamp if it were real - $2,250 catalog value and is very often faked. It can be manufactured by adding perforations to a trimmed #384, adding perforations to the left and right edges of a #384S or trimming the perforations from the top and or bottom of a #375.

The suspect has a single line watermark “U” at the top, it is impossible to determine if the orientation is normal or reversed.

The top edge is not parallel with the bottom edge and shows remains of perforations at the left side of the top edge.

There is no need to go any further with this analysis.

Conclusion: In my opinion the suspect is a Scott #375 with the top edge perforations trimmed away.

The perfin pattern, according to The Perfins Club, was used by the Chase & Sanborn Company, Boston, MA and is identified as pattern C408.
