|Continental Bank Note Company
US 162 - The round balls in the numeral "2"
Follow these steps in the
identification of your twelve cent Bank Note:
There is no need to check paper
type on this stamp, all 12¢ Bank Notes were printed on the
"hard white" paper, but you must still check
for the "secret" mark. If it
does not have the "secret" mark it is a National Bank Note
otherwise it is the Continental Bank Note printing, US 162.
If the stamp was printed by the National Bank Note Company,
check for grill to determine the US number. If the stamp has a
grill, it may be the rare US 140. If it does not have a
grill it is US 151. 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, although this stamp is
so rare that purchasing this stamp without certification is sheer
Watch for re-perforation (to fake a more well-centered stamp), for re-gumming (a major problem with the Bank Notes), and even
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 282 copies total of US
and 198 were sold, and they were never issued for postal use. 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 135 are known, they rarely come up for sale, except in
the sale of a major U.S. Collection.
