Just seen this excellent thread. Opportune as I am looking at Heligoland stamps.
Laziness and lack of expertise means I will post some for comments. Will of course supply UV data and backs/paper if anything looks promising.
I see that experts here are able to diagnose stamps from fronts mainly.
Thank you in advance for any attempts at ID!
I love the different shapes of her nose!!
Dear johnrcrow ! We continue, going from the easy ones to the difficult ones.
No 7. To be a genuine one, the perforation must be a. precisely 13 1/2 x 14 1/4 and b. the
paper must be the quadrille type ! This type of paper is built up by visible lines going vertical
as well as horosontal, making small quadrilles. It is easily seen from the back of the stamp,
holding the stamp against any lampe. If the paper is without quadrilles and perfotation 14 x
14, we are dealing with a Hamburg reprint, perforation 13 1/2 x 14 1/4 (without quadrilles)
indicates a Berlin reprint. My guess: a Berlin reprint, but let me hear.
No 11. The same problem: If perforation 13 1/2 x 14 1/4 precisely and quadrille paper it is
genuine ! If perforation 14 x 14 it is a Hamburg reprint, if 13 1/2 x 14 1/4 without
quadrille paper, we are dealing with a Berlin reprint. Leipzig reprint not possible because of
normal perforation holes.
No 12. If the perforation is 13 1/2 x 14 1/4 it can be either a genuine one or a Berlin reprint.
The colour could indicate a genuine one, but: we must examinate with UV-light. You can use
long waves or short waves. I think it is a little better with long waves. If genuine the red
carmine colour of the stamp will easily seen turn violet and the green colour goes to
greenish black/black. If a Berlin reprint the carmine goes to orange !! It is very easily seen.
If the perforation is 14 x 14 it is a Hamburg reprint, Leipzig reprint not possible because of
normal perforation holes. My guess: impossible without the result of the above mentioned
No 8. It is head-type I, therefore Berlin reprint is not possible ! The perforation holes are
normal, therefore a leipzig reprint is not possible ! Therefore: it can be a Hamburg reprint or
a genuine one. Now it is easy: if perforation 14 x 14, it is a Hamburg reprint ! If perforation
precisely 13 1/2 x 14 1/4 it is a genuine one ! My guess: both results are possible ! Let me
If it turns out to be genuine (13 1/2 x 14 1/4), there are 3 types: a and b are made of
quadrille paper, c is made of normal, not quadrille paper. a and b are more valuable than c,
but all the 3 are good. If you end in a or b, I can guide you further on via UV examination.
Now we come to the 2 worst stamps at all, regarding Helgoland stamps ! We will start with
No 16. This type has not Leipzig reprints. Start with perforation: if 14 x 14, it is a Hamburg
reprint. If 13 1/2 x 14 the outer colours will not tell us, whether we are dealing with the two
genuine types or the two Berlin reprints. We must use UV light. Now be careful: we ONLY
look at the colour-change of the red colour in the crown and the green colour of the
main-stamp, not the green colour in the shield ! If a genuine one, the crown colour will turn
very deep purple or very deep lilac and the main green colour will turn dark gray or deep
greenish gray !! If a Berlin reprint it is enough to look at the crown: the red colour turns to
orange or orange-brown, that is far away from the violet or lilac colours in the genuine ones
! Statistically we are dealing with a reprint, but let me hear.
Now we only have the worst of the worst to remain: no 6.
But I will take a little breake ! I will return.
