Need Help Identifying Two China Martyr Overprint Stamps.........

I've managed to identify all my China "Martyr" stamps - except for these two with double overprints - black/green.

Any direction on these would be greatly appreciated.

BTW, I'm using a new scanner and apologize if these are not the best of images.

Ask that you scan each stamp individually. So as to provide larger images.

Will look at the Ma (Chinese specialist) catalogue tonight. (Am in Pacific time zone.)

Believe what you have is Scott 619 and 622. They are part of the "CNC Surcharge" grouping.

The basic stamps are from the (secret marks) Martyr Issue of 1940 - 41. The first surcharge (black rectangle) signifies the Nanking puppet government's currency. The second surcharge (green) signifies Chinese National Currncy (CNC), and is believed to have been applied in 1945 at Shanghai.

Both stamps should be sans watermark. And perforated either 12.5 or 13.

Both are minimum catalogue value.

Hope that helps.

Thank you!
I didn't recognize the 3rd value...........do you know which symbol it is?

Don't understand the question.

My error. The 2-cent dk blue is Scott 616, not Scott 622.

Hi,
Calstamp, when I looked up the numbers in Scotts I saw that it was 616 - but you sure got me in the right direction!
I did some browsing on Chinese number characters and printed out a list. That is a big help.

For years I just kept the Chinese stamps I couldn't find a home (in Big Blue) for in glassine envelopes. It was just too complicated for me. But suddenly a couple of weeks ago it has become almost an obsession........and with all the Steiner pages, I am slowly able to fit them in the proper squares.

I turned 75 early this week, and realize this is one hobby I can love and enjoy for hopefully years to come!

Thank you all!
