1 Kopeek ,1865 , M#12y, Russia- Diferente Paper Type ?

Can you please coment this ,Mi # 12y ,1 kopeek ,1865,Russia ,used .
The stamp is with some kind of line patern in the paper that shows fine vertical lines running through it's back.
The thin vertical lines of the paper can be distinguished more clearly when looked from a distance. Could this stamp had been printed on ribbed paper and did someone encountered more "ribbed printing"stamps ,from these or other issue from the same period?

Your stamp is on laid paper.

The question was not referring to the lines of the watermark ,which are traditionally present in laid paper itself,but the uneven sections in the paper which are visible on the first images.
The image posted below below is of
a 1 kopeek,Mi # 18y ,1868,Russia stamp,on vertical laid paper. The paper looks flat.

@post_pe, if anyone knows anything about Russian stamps, it is rogdcam.

I'm sure tath rogdcam,has more knowledges in Russian stamps then other members of the forum.
This is the second stamp I have saw that's showing some sort of ribbing on it's back. The other stamp is ,from 1902, but the ribbing is not vertical it's horizontal. I understand tath this lines may have appeared there from many reasons .I'm only trying to collect more information about the stamp.

You might need to get a specialized Russian catalog ?


Peter

Watermarks are not traditionally present in laid paper. One has nothing to do with the other really.

Your choices for this stamp are unwatermarked perf 12.5 wove paper, unwatermarked perf 14.5/15 wove paper, watermarked perf 14.5/15 horizontally or vertically laid paper. The watermarks can also be oriented in both directions.

If you are saying that there is an amplitude to the vertical lines then I would suggest that your stamp was stored in some manner or came from a cover that impressed the paper with lines. Zagorsky, Zverev and others record no such ribbed paper ever being used.

Hope that is helpful unless I am still missing the question.

Your first stamp looks like the 1866 issue on corrugated ordinary paper. ? It has the broken frame variety in the upper right corner...

Peter, I have checked Michel Specialized Catalogs of Russian stamps .There is no such type of variety pointed there .

rogdcam,tath was precisely wath I meant . You were completely right by correcting my post regarding the watermark on these stamps.
Yes my question was concerning the vertical lines . I have also checked these two catalogs which you've mentioned in your post and a nother Specializet catalogue- this of Soloviev,but unfortunately there were no records of such type of paper been used at this or other issue, from this period. Of course I can't exclude the possibilitie tath the stamp was simply glued on a envelope tath had a horizontally ribbed pattern which impressed it itself on the back of the stamp. I can't be certain wath is the reason, for the presence of this lines there. I only share my observations .
I came across to a Polish stamps ,from 1919 tath were printed both on ordinary and ribbed paper,but these varieties are well known and are described in literature. Could a very small quantity of some Russian stamps issues,have been printed on ribbed paper ?

These are the Poland stamp I wrote about .The stamp at left is printed on ribbed paper.

This Russian stamp,from 1902, also has a" ribbing "patern on it's back but it's horizontal not vertical.

The original posting caught my eye as I recently worked through a small collection of similar-period material. And as is often the case, discovered a number of stamps which had been misidentified (by me) previously. (That's the problem with knowledge!)

Have read through this discussion thread twice, and remain confused as to post_pe's continuing queries. IMO rodcam's posting of 12:20 yesterday clearly lays out the options.

Conclude all philatelists are "treasure hunters" to some extent.

Post_Pe - You can rest assured that your stamps were not issued on ribbed paper. The stamps of Russia are heavily collected and studied and every variety has by this time been cataloged and collected in extreme detail. That leaves handling/mounting/storage as the culprits. Could have been the material it was mounted on or how it was pressed when drying IF as I said the lines have amplitude in the "X" axis. IMO the topic is pretty much exhausted at this point. Yes?

Rogdcam,tank you again, for participating in the discussion. I have changed my mind and now I accept that the explanation offered by you is the most logical one .
I was just curious to hear as much as possible opinions on the stamp.
