Caution:
Scott 445 is often faked by cutting off the perforations on a
Sc426. The fakes usually measure smaller than the desired
25mm tall and are therefore not very convincing, but taller
fakes can be a problem. Taller fakes can also be made from
the imperforate Type I stamp Sc483. Although the 483 is
unwatermarked, it may pass detection if the watermark is not
checked. Be aware that fake watermarks do exist on this
stamp. We would
advise buying Scott 445 only from reputable sellers. Better centered copies and line
pairs are particularly suspect; we would recommend buying or selling these
only with certification. In all cases make sure the stamp has a single-line
watermark.
