Follow these steps in the
identification of your ten cent Bank Note:
You will need to check for the "secret"
mark , which is fortunately easy to spot. If the stamp has the "secret" mark,
determine the type of paper
it was printed on, if it was printed on the "hard, white"
paper it is the Continental Bank Note printing, Scott 161. If it was
printed on the "soft porous" paper, it is the American
Bank Note printing, Scott 188.
If it does not have the "secret"
mark, check the paper type. If it was printed on the "hard, white"
paper it is a National Bank Note printing. If the stamp has a grill,
it may be Scott 139. If it does not have a grill it is Scott
150. Care must be taken when authenticating the grill. Many fake
grills have been added over the years in an attempt to increase the
value of the stamp.
If it was
printed on the "soft porous" paper, it is an American Bank
Note printing. If the stamp does not have the "secret"
mark you will need to check to see if the stamp is the original 1879
printing, Scott 187 or the
re-engraved stamp, Scott 209. See the illustration above for
details. Scott has
given the re-engraved stamp a sub-listing, Scott 209b for the black brown
shade.
If you are unsure of the type of paper used or of the secret mark, you
MUST assume that the stamp is the more common variety. If the stamp
is unused and has at least partial gum, this stamp should be
certified to ascertain the type, since the value of the stamp will
in most cases far out weigh the cost of certification.
Watch for re-perforation (to fake a more well-centered stamp), for re-gumming (a major problem with the Bank Notes), and even
for bleaching
of the cancellation (to remove the cancel). Unused copies carry a
substantial premium over the used stamp.
We include the "Special" printings in this identification
guide merely for completeness. Only 180 copies, total, of Scott
172
and 197 were sold, and they were never issued for postal use and
were issued without gum. We occasionally see uncertified copies of
these stamps offered for sale at ridiculously low prices. You can
rest assured that the stamp being offered is not genuine. These
stamps are so rare, only 70 copies are known, they seldom come up for sale, except in the
sale of a major U.S. Collection.
