well, at least there is something going on about the perforation, and I think this is the reason AhmCvv asks about this stamp here - should have chosen another title and text.
the perforation at the bottom is different from the top, maybe perf 10, you should use a perforation gauge. still, it looks a bit strange, so a better scan would be needed, especially without image processing to see the borders better.
so I would do further investigation about this stamp.
Interesting. So it appears someone may be on a fishing expedition? Out of curiosity regarding that census report, do they list catalogue or selling values for the items listed. I do not have a copy and am unaware myself.
This thread was flagged by another member as suspect. We want to give folks the benefit of doubt and try to not assume anyone's motives. Hopefully the OP will come back and let us know the purpose of his original question, 'how much is the value of this postal stamp'. Perhaps he is considering buying this stamp, perhaps he owns it, perhaps he was up to something 'less than good'.
