According to my SG Collect British Stamps the 2d blues with plate numbers were plates 7, 8, 9, 12 ,13,14 and 15, there are of course others without plate numbers.
Presume you are enquiring about the GB 2d Blue.
According to my older Stoneham The perforated stamp with letters in lower corners only came with plate numbers 4,5,6. all on bluish paper, plate 6 also came on white paper.
Below is a scan of the section in the catalogue that applies. Note there are different watermarks, perfs and alphabets. Columns 6,7,9, with column 10 being the plate number
Hope this makes sense, unless you are asking about those with letters in all four corners.
Two penny blues are kind of tricky. Just figuring out which issue they are from is sometimes difficult, yet alone determining the plate they came from.
If they have "stars" in the upper corners there is no plate number in the outer frame and can be from plates 1 to 6. The stamps with letters in all four corners have the plate number in the outer frame and were printed from plates 7, 8, 9, 12, 13, 14 and 15.
First are they perforated or imperf?
The imperf 1840 2d can be plates 1 or 2. The imperf 1841 2d can be plates 3 or 4.
The perforated 2d issues can be from plates 4, 5 or 6. Plate 4 is only on "small crown" watermarked paper and can be either perf 14 or 16. Plate 6 is only on "large crown" paper and can be either perf 14 or 16. Plate 5 was used with both small crown and large crown papers and both perf 14 and 16.
So as you can see, just figuring out the correct catalog number is quite a bit of work.
There are several specialized books and catalogues that can aid in determining the plate number. Stanley Gibbons Specialized Part 1 Queen Victoria is a good starting point. Seymour's "The Postage Stamps of Great Britain Part One" is good for the imperforate line engraved issues, both 1d and 2d. Wiggin's "The Postage Stamps of Great Britain Part Two" is helpful for all perforated line engraved stamps not just the 2d blue. Both of these books are out of print. There are a couple of books just on the 2d blues, such as "BRITISH LINE ENGRAVED STAMPS: TWOPENCE BLUE STUDIES OF PLATES 1-15" by Osborne which is out of print and "TWO PENCE BLUE: PLATING GUIDE" compiled by Mike Jackson which came out in 2010.
Sorry for the long winded explanation! The short answer is plating Great Britain line engraved stamps is an art form and is challenging, to say the least.
Posting pictures of the stamps would be helpful. I hope I haven't confused the issue with too much information.
I'm not an expert at plating by any means, but if you have any questions feel free to PM me. No promises.
Thank you to all who have responded to my question I think a better understanding is in the forecast for these tricky issues,thanks again Rich
I have many 2d blues which do not appear to show the plate numbers in the outer frame for example I have from an earlier collection stamps identified as plate,4,5,6 but for the life of me can not the plate numbers.Rich
