Cut Versions Of Stamps Shown Here

Hello,
at the beginning I thought I would ask a question about blueish paper :). But now I learned that my perforation is wrong for that :(. Well, still I would like to know:
- what stamps are these 2 below (1 cent), with 1 side cut and no perforation? I don't find them in my catalogue. Perhaps someone has a link or a scott or Michel number?
(the 3 cents one I think I found)

thank you

Hi joker and welcome to the forum. You're three months early!
To help you out a bit, the 3 cent is a coil stamp with the two vertical sides un-perforated. The other five stamps are all regular ones that are in the Scott catalog. The ones with one side straight are edge pieces, resulting from a large sheet cut to make four smaller panes.
If you go to http://stampsmarter.com you will be able to ID your stamps.
The 31 cent Airmail is C90 in the Scott catalog.

hello Peter and thank you!

yes that helps already. So nothing spectacular, right?
I forgot another one that I attach here, sorry for the bad photo but I guess you can see it. Also just a normal one?

the link does not work?

about the blueish paper (5 cents, which is none...): do I have any chance to see this paper and the rag in a deep scan? or is this only for professionals?

The best way for the average collector to detect bluish paper is to scan the candidate stamp (the "patient") side-by-side with a known non-bluish stamp of the same era on orange paper. Using high resolution is a good idea. The scan at the start of this thread is not large enough to determine whether the 5c stamp is bluish, but also does not eliminate it from contention - it is ambiguous.

Detecting bluish paper on the basis of ultramarine crystals embedded in the paper, or other particles or signatures, requires high-power magnification and experience. There is an article in the October "United States Specialist" in which this was done (available from the United States Stamp Society) with inconclusive results with respect to the source of the bluing (in my opinion).

Joker, Chris wrote a good post about bluish paper above. But on this forum are several other posts, some of them with scans of stamps on bluish paper. Search this forum for "bluish paper" if you are interested. A "search" button is on top of this page. I must warn you though, it is much more likely that you get hit by lightning than that you find a stamp on bluish paper!

hello again,

--- thank you that helps :).

I also made some photos, where I really saw like rag, blue things and so on. but as I said, the perforation doesn't fit...

but I have another question: the red 2 cents is perforation 11, which scott number could it be?
