1. If the stamp is perforated 13½ x 14¼ with large holes
and is on quadrille paper it is an Original (Scott #10).
2. If the stamp is perforated 13½ x 14¼ with large holes
and is on white to light cream smooth paper, it is one of the
three Berlin Reprints. These can be separated by color in
ordinary light and in ultra violet light although this is diffi-
cult without examples for comparison.
3. If the stamp is perforated 13½ x 14¼ with small holes,
it is the Leipsig Reprint.
4. If the stamp is perforated 14 x 14, it is one of the three
Hamburg Reprints. These are very difficult to separate un-
less examples are available for comparison.
5. The 2nd Berlin Reprint (May 21, 1879) of 5000 stamps was
delivered imperf. Since the imperf. stamps did not sell well,
those remaining were returned to Berlin and perforated with
the regular 13½ x 14¼ perforation on May 30, 1884.
This resulted in 800 imperf. and 4200 perforated stamps.
