Caution
Both Scott 449 and Scott 453 may be faked. We would advise
purchasing these stamps with certification only, particularly Scott 449.
Neither of these stamps
are prime candidates for fakery, since there are no other Type I stamps that
they can be made from. The best fake of the Scott 449 would be made from the
Type III, Scott 450 stamp. However, there are so many differences
between the Type I and the Type III stamps, it is nearly impossible
to fool anyone willing to take the time to examine the stamp closely. The
buyer would be well advised to buy the Scott 453 from a reputable dealer
only and remember: SCOTT 453 MUST HAVE A SINGLE-LINE WATERMARK.
