Any China Collectors Or Experts Here

SG1132. Top frame distorted.
SG1155. Top of 5 Deformed.
SG1162b. Kiss print.

SG1474 I think. It has a yellow overprint that I cannot find listed. I can see tiny traces of red. Faded/altered ?. Heavily damaged.

SG1487 with a line top outer margin. Heavy damage.
SG1621 with lines in the outer margins. Double lines visible lower left.
SG1622. This one has a sort of multi curved line running through the building. Also top and left. With a dribble lower right.

SG1626. Triangular mark on shoulder and several breaks in the frame lines.

SG1779. Another one with the top of 5 deformed. This one on the underside.

SG2010. Part of the left side of the building is missing. The paper looks scuffed, so could just be damaged ?.

And finally.

SG3943(MS). Two stamps used on piece. The lower stamp has a misreg of the colours. making the horizontal lines appear doubled.

I hope you find the above stamps as interesting as I do.

Dynamode, until Communism took over, I believe Chinese postmasters all over the country were allowed to change the values of the stamps (within reason) to suit the immediate needs. It shouldn't be a surprise to never be able of identifying all surcharges.

I think many of these varieties are printing effects or maybe some of them are the common characteristic of a given position in the plating. As far as I know, nobody really did an extensive research on the plating of coiling dragon and later issues. There was some research done of the large dragon, red revenue and some small dragon issues. Nobody even re-constructed the small dragon plating. Therefore, for most of the stamps, only some very distinct varieties are paid attentions to and included in the catalog. So, really, I don't know anyone can answer your questions.

As for the gold yuan overprint stamp, it looks genuine to me. The overprints were added so poorly that many were misplaced in different ways. Your copy actually looks perfectly fine.

aug-stamps, Tang Stamps thanks.

I would not expect most of the above to warrant a catalogue listing. But you never know. Unitrade lists all kinds of little dots and marks as varieties. Maybe other catalogues do as well.

Maybe this post will tempt people to look at their stamps and compare. They are here now for all to see.

Maybe in a years time someone will say, I have one exactly the same. Lots of maybes.
