#30A Pirie Paper - Coriandre

I would appreciate an opinion on the following ;
I have 2x#30a (see pics)
the darker one looks brownish/ dark greenish on a "normal" color paper
the other one is obviously green-gray on an off-white paper

Both are perf 11 1/2 x 12
Both are on wove paper

Documentation says PIRIE paper is greenish gray, wove paper, with diagonal grid...

Which is which??

Note : the colors of the second one are more vibrant giving the impression of being printed on a glass-paper

Practically all postage stamps ALLOVER the world - since 1860 - have been printed on machine made paper and machine made paper always had diagonal grid until at least 1938! All machine made paper has a wove! Either symmetrical or asymmetrical [since 1938 the asymmetrical wire can be found used in paper mills next to the symmetrical wire].

That your stamp has wove paper and a diagonal grid just tells you as much that I have got hair on various parts of my body... Philatelic non-sense to be diplomatic!

Wiggins Teape in the UK had the Alex Pirie paper mill, so the paper is English [Scottish]:

Re : the note after my topic. When refering to the colors, I mean the front of the stamp...of course!

This is the 15c LQ on Pirie Paper. The front shows the Greenish Grey shade (I have also seen this stamp in a brownish grey shade) and the back shows the weave and the watermark at the top. Menich reports this as being on an unusually thick paper (.081 - .107) but I don't find it being that thick. I'll have to try and measure. Normal paper is .030 and thick paper is .040 or higher.

Notice that you can see the design from the back on both your stamps so they are both on thin paper.

Hello Koala. Funny that you call out my name as I have not checked this site in a few months ! Nice stamps ! To me, both your stamps are on the same paper type. The difference in shading (of the paper itself) is from the tinting that occured thru out the years. I think the first one might actually be a 29a (hard to tell if the shade is greenish or leaning towards violet). The second one is surely a 30a. Lucky to have the fine example from Jimjung that clearly shows the difference in paper. 30a is from 1873 and 30d from 1876. It is the first time that I see the actual script on a stamp. Is it the "s" from "sons" upside down Jimjung ? Unwatermarked copies of the pirie paper also exist although they are not listed in Unitrade.

Coriandre : thank for your answer

Surprizing isn't? So far, you are the only person I know on this site who knows a lot on L.Q.

I am sure there are many other people who have a certain expertise on this matter and I would appreciate to hear from them.
It will be to the benefit of everybody

Coriandre - I have owned this stamp for a long time and researched it well years ago. You can see that it has a HALIFAX NS postmark dated AP 17 76, perfect for the variety. The watermark appears inverted on the sheet and I have found the exact position of mine as marked in this drawing I created from the Duckworth's book.



There are alot of LQ experts here but I'd say most are interested in the plate varieties. The 15c LQ is a big study. I'd like to get the Firth book on the 15c LQ. A whole book on one stamp!

i am no expert Jimjung and Koala. I just really enjoy the LQ and have studied them quite a bit. The 15c and the 3c are my favorites.
The watermark on your stamp is exactly what I thought....the upside down "s". You are lucky to have this stamp. It is worth a pretty penny and you rarely see any for sale. Did not know about the Firth book. Great to know !

I really love the LQ's also and I consider myself endlessly learning more about them.

Koala - the thin paper stamps, especially the perf 11 1/2 x 12 are preferred examples of the Large Queens.

Here is a nice block of the 15c. If you look closely at the left margin, you'll see a Kiss Print showing a 2nd image of the left side of the stamp design and a 2nd image of the imprint.
