Trying to sort through Coil Stamps 1610 - 1617.. Do all coil stamps in GDR have 2 straight edges. Seems like a dumb question to myself but I have the 1611 neptune fountain (size 21x17mm) and this is the only place I can see to put it. But my stamp has perfs on all 4 sides
No, those German coils were produced differently from US coils. Therefore, you will find them perforated on all 4 sides.
On some issues which were distributed in both sheet and coil formats, there is a trick or two to help figure out if you might have a coil. But in general, the only real guaranteed way is having a coil stamp that has the control number on the back.
The above statements are "generalized".
And no, that is not a dumb question at all. I asked myself the same question when I first saw some supposed German coils. So I'd like to think it's not a dumb question (I hope).
ok...that is great - that means I won the verbal war at our house on this one My better half was sure I was wrong... And yes we have the control number as well on the stamp...
Thx...
