1946 China Airmail C42 73/25 - Help With Identifying

Hi there guys! I'm entirely new to the stamp world and decided to begin the long journey of trying to assess my Grandpa's old collection which I've had since his death about 30yrs ago. So he did everything in a Minkus collection - I'm having difficulty identifying these. I came across this 1946 China Airmail stamp and was wondering if it's the valuable of the 3. It's apparently unwatermarked - or in the unwatermarked slot - although out of care, I haven't unhinged it yet. (Although it is in a mini-sleeve - - so is it considered hinged?? Side question...) Anyways - your help would be so nice and I may need a lot more help as I'm going through this gigantic world-set. I'm interested in selling and that's why I'm beginning this task. Thank you so much!!
(I also couldn't seem to accurately count the perforations.) To me - it looks exactly like this specimen where it sold for a nice mint. http://www.interasia-auctions.com/c...t=811&lang=1

Hi and Welcome! very lovely stamps. I am not sure on the value - however there are many experts here to help. I would love to see more of your Grandfather's album - from looking at the quality of those, I bet it is fantastic. Again welcome!

Nora.

Thank you Mrita! Excited to be here! Yes he was fanatical about details and keeping things tidy. Every stamp I'm finding is in amazing condition. Thanks again! -J.

Hi Jeruel, and welcome. One of the first things to do is get a perforation gauge. Your grandfather certainly had one? First thing in IDing stamps is gauging the perforations, not counting them!

I am not an expert on Chinese stamps but I have once Identified the orange 73$ with overprint of how much it costs in gold currency. I seem to recall it had a nominal value of a few pounds in the Stanley Gibbons Catalogue which in reality means its not worth much at all, but it's still a nice stamp. They were issued just by the Kuomintang government before the Communist ousted them.

Thanks! I'm sure he had a perforation gauge but he passed 30yrs ago and I don't have one. I'm just mainly trying to see if anyone can shed light on this specific piece in order to verify if it's the one valuable variation of the 3. Thanks!

Thanks Rod - I assume you mean it's the higher value of the 3 versions? (Regarding the 3 similar yellow/orange versions..) Thanks again

Apologies, my bad,
I thought I had deleted my post, but I guess not, due to the lag here at SCF.

I was lazy, and did not read all your post, and needed to check the print.

You actually shot yourself in the foot, you should have posted your query on the other thread that showed Tony's ID assistance.

We read all posts, making another thread does not help, it probably hinders.
I'll go back and see if I can get an answer.

Ok thanks

Re-assess your stamp using the chart Jeruel.
check the perforation guaging,
It looks as if the character is "not Joined" indicating the Hong Kong print
Check to see if Perf 12-13

The general rule in Philately ID, is "Assume your stamp is the cheapest version" but go ahead and try to prove otherwise.

Author :Tony : Chan lists either type at $1, as against $2000 for the Peking printing.

Thanks a lot Rod! I had seen that on the other post too and noticed mine is not adjoined. I've scanned various auctions and it seemed that many demanding a premium also did not have that specific character adjoined which is why I continued this analysis. Is there any way anyone might be able to give me an idea of the perforation count? I've tried myself and I honestly keep coming up with 15! I've gone through the various instructions on how to count the teeth etc. - but I figured maybe more adept collectors may be able to tell me? Thanks again everyone! (I posted here because I didn't want to overtake that other thread.)

When clicking the first image in order to enlarge it - the perforations are more than clear. I just don't think I'm counting them right ??

You will need a Perforation guage Jeruel, counting teeth does not
work.

If you are accurate, and measure the design of the stamp ONLY. across the width in Millimetres (mm).
I can work out using math.

The gauge of a stamp is the amount of punctures in 20mm line of punctures.
When you see a perforation guage, they are all 20mm wide with black dots.

Adding to an existing thread, with a like-minded query, ADDS to a knowledge base.

Using another thread promotes entropy.

Ok thanks on both accounts Rod! :)
