Russia 10r 5th Anniversary Of October Revolution

Not Pelure, but could be thinner than normal issue.

To put things in perspective Zagorsky in his seminal catalog of Russian stamps lists two thicknesses for this issue. The first has a range of .07 - .08 mm and the second has a thickness of .07mm. In my experience neither of these are the "pelure" paper. The question is why Zagorsky doesn't list the really thin paper stamps. Neither does Zverev.

Wow... I think that perhaps it could be because although you can find papers so thin that they might look like pelure, they really aren't "pure" or "real" pelure. Pelure doesn't exist in the 5th Anniversary issue, but rather very thin papers below the 0.065 range... it's a theory.

To recap:
two papers from the 5th Anniversary issue, thick and thin:
one thick, spongy, and opaque;
the other, thin, smooth, and transparent.




Now, an authentic Pelure from another issue I'm studying, .. This is an authentic Pelure.



Now, looking at the examples of paper from the 5th Anniversary issue (I think the complete difference is noticeable for all us), does an authentic Pelure exist in the 5th Anniversary issue? Well, it could be... Now, does authentic Pelure exist in the 5th? Where does the thin, transparent paper fall? I think the answer points to thin paper below 0.065, which is equivalent to said "Scott´s 5th Anniversary Pelure".

Title modified by Moderator to clarify that this thread is about a Russian Stamp. This may help to locate this thread in a future inquiry.

Rizla Black, the "micro-thin paper for the expert rollers", is 0.02mm in thickness, weight of 13.5 grams per square metre. Discounting the licorice-coated paper, there's eight papers in the range; with Rizla White being the thickest at 23 grams per square metre. This range of papers would be useful in calibrating the micrometer that someone's just ordered.

I took this Zagorskiy catalog clipping from another thread of Russian stamps. I think the classification by thickness is more effective than Scott's definition of "pelure." This brings me to the stamp at the beginning of the thread, the 10r, which undoubtedly falls on the fine side, compared to my other 5r thin and 5r fat examples, not only because it is obviously fine, but because of its peculiar texture, just like the 5r thin. Transparency can be a good indicator, but not the definitive one, since I don't think this issue even reaches its finest point in pelure, and 0.065 might not seem transparent enough.
