Suspect Scott #352, Unused HH Single (10/11/15).

If real this is a modestly expensive stamp with a Scott Catalogue value of $220.00 for a used single. The Experts Book states that the #353 is often faked by adding perforations at left & right and trimming top & bottom a Scott #344, adding perforations at left & right to a Scott #344S or trimming perforations off at the top & bottom of a Scott #332.

The watermark is double line “S” at the bottom and “U” at the top, reversed, inverted and reads horizontal which eliminates the possibility of the suspect being made from a Scott #332a booklet single.

The height of the suspect is a short 23.75mm.

The images below show the suspects perforation overlaid on genuine perforations. As can be seen the suspects perforations are a poor match with the genuine perforations. As can be seen from the images below the suspects left and right perfs match the known genuine perforations. The left perforations gauge out to 11.94 and the right perfs gauge at 11.97 which is within the range of tolerance. The perforations show the signs of being genuine.

This is an image of the perforations that have been flipped on themselves and as can be seen they have major fit issues.

Conclusion: In my opinion the suspect is a trimmed #344 with counterfeit perforations added to the left and right.
