|Follow these steps in the identification of your One Cent Bank Notes:
Determine the type of paper the stamp was printed on. If it was printed on the "hard white"
paper it is either a National or Continental printing. If it was printed on the "soft porous" paper, it is an American printing.
If it is an American Bank Note printing, compare the area near the arabesque with the illustrations above to determine whether it is US 182 or US 206.
If it is either a National or Continental Bank Note printing, check for the "secret"
mark. If it has the "secret" mark it is the
Continental Bank Note stamp, US 156.
If the stamp was printed on the "hard white" paper and
does not have the "secret mark", it was printed by the National Bank Note
Company. If the stamp has a grill, it may be US 134. If it
does not have a grill it is US 145. 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. US
134 is common enough that it may not be necessary to certify
all copies, but nicely centered, fault-free, and particularly unused
stamps should be certified.
If you are unsure of the type of paper used or, more likely, of the secret mark, you
MUST assume that the stamp is the more common variety.
Watch also for removal of the
secret mark by scraping, 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).
We include the "Special" printings in this identification
guide merely for completeness. Only 388 copies, total, of US 167
and 192 were sold, and they were never issued for postal use. All
were printed 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 rarely come up for sale, except in
the sale of a major U.S. Collection.
