1. If the stamp is perforated 13½ x 14¼ with large holes and
is printed on thick quadrille paper, it is an Original (Scott #11).
2. If the stamp is perforated 13½ x 14¼ with large holes, the
paper is thick soft wove paper and the fine frame lines are unbroken,
it is an Original (Scott #6).
3. There are two printings each of Scott #6 and Scott #11. Check
in ordinary and ultra violet light to determine which is which. This
is difficult unless examples are available for comparison.
4. If the stamp is perforated 13½ x 14¼ with large holes, the
paper is thin grayish white and the fine frame lines are broken, it
is one of the three Berlin Reprints. If it is perforated as above
except with small holes, it is the Leipsig Reprint. If it is perfor-
ated 14 x 14, it is one of three Hamburg Reprints.
5. The 2nd Berlin Reprint (May 21, 1879) of 5000 stamps was deliver-
ed imperf. Since the imperf. stamps did not sell well, those remain-
ing were returned to Berlin and perforated 13½ x 14¼ on May 30,
1884. This resulted in 800 imperf. and 4200 perforated.
