Suspect Scott #443, Unused HH Single (5/10/14).

The Experts Book say that this coil is often faked and can be made by adding perforations left and right and trimming the top and bottom of the imperforate #409, by adding perforations to the left and right of the imperforate coil #409H and trimming the perforations off at the top and bottom of the fully perforated #425. Catalogue value: $50.00.

The watermark is an inverted normal S that reads horizontally.

The height of the suspect is 24.75mm tall at the left and 25.125mm tall at the right, the edges are not parallel with each other never mind the frame.

The images below show the suspects perforations overlaid on genuine gauge 10 perforations.


As can be seen the suspects perforations do not match the known genuine perforations.

There is a possibility that the suspect is a rotary press #453, #454 or #455 which are also single line watermarked issues.

As can be seen from the above image the suspect is a flat plate printed stamp.

Conclusion: In my opinion the suspect is a trimmed Scott #409 with fake perforations added on the left and right edges.
