After each coin has been graded and the necessary
numbers and text entered into their respective
data fields, the coins in a particular box are
taken from the Grading Department into the Encapsulation
Department. Here, labels are printed out bearing
the following text: The coin's date, mintmark
(if any), denomination, variety (if any), grade,
special designation (such as FB for "full bands")
and, finally, its identification number. This
last item is extremely important, as it serves
to make each certified coin label unique. It is
also an important deterrent to the counterfeiting
of NGC's valued product. All of the above information
is duplicated in a bar code, which appears underneath
the written text on the coin's label.
The newly-printed labels are matched with the
coins to be encapsulated with them. The coins
are now ready to be placed inside a plastic core
piece that holds it securely within the transparent
holder. NGC maintains a wide assortment of these
white cores to assure a proper fit, each having
a different size opening to allow for the many
United States and foreign coin types certified
by NGC. The core, like other components of the
NGC holder, is made of inert material that won't
adversely affect the coin it holds.
 Once
this is accomplished, each certified coin has its label positioned in
place on the core, and these components are then enclosed within matching
top and bottom shells of transparent plastic. First, however, all of the
pieces, including the coin itself, are blown free of dust and other contaminants
by a jet of compressed air. This process is used one more time when the
shell pieces have been sealed around the core through a combination of
compression and ultrasonic vibration. The result is a newly-encapsulated
NGC certified coin, ready to be shipped to its proud owner.
