Suspect Scott #446, Unused MNH Pair.

I examined this pair for a colletor friend.  According to The Experts Book this stamp is sometimes faked and can only be manufactured from a #427 by trimming the perforations off at the top and bottom edges. As a side note the #427 does not come in booklet form and there is no single line watermark flat plate imperforate stock in which to make a fake from. The only imperforate stock is the #346 but it is double line watermarked and a fake made from it would not fool anyone. The #446 can be confused with the single line watermarked rotary press printed #457 or in rare cases the unwatermarked rotary press printed #495. A search of the Philatelic Foundations certificate database found 634 issued certificates with two being misidentified #457 and a single misidentified #495. The catalogue value is $700 for a unused MNH pair.

The suspect is single line watermarked with a reversed U and S that reads horizontal.

The suspect is also flat plated printed.

Because of the flat plate printing and the single line watermark the perforations can only be genuine and the straight edges need only be examined.

The top and bottom edges do not show signs of recent trimming see images below.



Conclusion: In my opinion I felt very confident that the suspect is indeed a genuine #446, MNH pair, I advised my friend to have this pair expertized. My friend sent the pair to the Weiss Expertizing Service and got a certificate back stating that the suspect was indeed a genuine #446 Unused pair that had been regummed (I missed that part).
