Help With Group Of Russian Stamps

I have obtained this small group of Russian stamps and I would need your help with two questions:
-Firstly about SC#211 of which I have two copies, the one on the left in an evident thick and fluffy paper; The one on the right is a thin, very smooth and more transparent paper. Could this be plelure paper?
-Second, it is about the last two stamps in the photograph that belong to the models SC#62 and SC#75, the problem is that they are imperforated and that does not appear in my catalog...the size in comparison with the perforated models corresponds, in fact it does not seem that they have the perforations cut...

Your bottom imperf stamps are Scott 121 and 125. By your description, the 211's are indeed 211 and 211a and the gum wrinkles on the pelure paper stamp are typical of that.

I have some doubts regarding rogdcam's comment on pelure paper. Pelure paper is very thin and very transparent. This stamp does not look that way from the scan.

To assuage Danko's doubts post a scan of both with backlighting.

The model without wrinkles in the gum, appears thinner, transparent and smooth... it is like a mint bill, it has sizing and you can make it "snap"

It is clear that they are two different papers...I think this because of the visible mesh of the stamp without wrinkles in the rubber. I'm still learning, but I would say Rogdcam are right, the model with wrinkles in the rubber is the pelure paper, I am enormously surprised!! I wouldn't have bet on it, in fact it was a discard that I had in a secondary album waiting to get another copy to compare.

I collected these. The one is pelure. There are always doubters.

Okay!!! the mesh is pelure!!! Thank you very much for all the help!!!

Sorry to doubt you, but I still believe this is regular paper not pelure. Pelure paper does not have a mesh. It is uneven in thickness, and when you place the stamp on the black background the paper would look grayish/dirty. That is because of the black background showing through the thin parts of the paper. If you place the stamp against the light, you can barely see the design because light shines right through it.

The pelure paper looks as transparent as wet napkin when you look at it from the back.

Not a specialist in this area, but I believe this stamp was issued using different paper with different thickness. You have thinner and thicker paper but none of them are pelure.

I'm out.

100% false.

See this lengthy discussion about pelure paper:

Maybe I'm expressing myself wrong... I don't want to say mesh like an engraving... but rather I say it because of the lighter points that can be seen distributed evenly across the entire surface, only visible in very strong backlight, as seen in the photo.
I consider that it could be fake because it is very well made and printed compared to other copies I have seen, just like my other stamp. but at first I discarded the idea.
Now the possibilities open to having two different papers are: One must be Pelure; or that one is authentic and the other false.

Forget about the mesh. Seeing a mesh pattern means nothing. Read the lengthy topic I linked above. This is a simple topic with a simple answer. At least it was until someone came along with bad info.

Your stamp is not fake. It is pelure paper.

I think it is pelure, too. Pelure paper is very obviously different. I have a handful of this exact stamp, both pelure and not pelure. When viewing from the back, virtually the entire design shows through.

Edit: Going to do more research first. There are some German stamps that are pelure and I recall them being virtually transparent, like being printed on clear plastic. Those are much different than the stamp shown here.

The stamp paper in Michel is called "Zigarettenpapier"
Is it pelure paper?

Yeah, those are the stamps I was thinking about. I thought the Scott catalog said they were pelure. I'll double check tonight.
