Caution:
Scott 350 and Scott 354 may be faked by
trimming Scott 334 on the
appropriate sides or by adding perforations to the imperforate Scott
346. Since the unused copies of 334 and 346 are reasonably
expensive in their own right, one wouldn't expect to see that many
unused fakes of Scott 350 and 354, however, unused fakes are not
that uncommon.
It is
quite likely that the used stamp could be a trimmed fake of a Scott
334. We
would advise purchasing used copies of these stamps with certification or from
a reputable seller only and to view any used copy of these stamps with a
heavy dose of suspicion, particularly well-centered copies.
Be sure to watch out for guide-line pairs, fake guide-lines are
often drawn in, but the fake line will not pass the "engraved"
test.
Once again, the stamp must have a double-line watermark. A quick
watermark check will eliminate any fakes made by trimming the
single-line watermarked Scott 377 or any other 4¢ stamp for that
matter.
