Couple Of Great Britain ID - Please

I have a couple of GB that I am wondering if the ID can be ascertained without my having to take them off the page. Less intrusive with this book, the better. Any information would certainly help Scott number or near value.. (As always just tell me a) you can retire now or b) don't quit your day job) thanks - Jeff

The top one looks like a 'White Lines' issue of 1841.
The paper looks blued.
However, the cancel is very splodgy and the top left corner is eaten into.
I reckon about one tenth of catalogue, which is £70. So say about £7.
SG#13, Pale Blue.

Second one is 1858-79 issue with Plate numbers. Yours looks like 82 which is £4 used although your copy has defects. 50p at a guess !

Londonbus1....the not very helpful

The bottom stamp is SG167.
Issue from 1880-81, Venetian Red.
Catalogue is £10 but again your copy has defects. Not much more than a pound I'd say, or $1.50

Sorry, you won't be a millionaire tonite !

lb1 was looking while reading your explanation. Lifted stamp to check blue. Appears to be postcard square. What does that do to number 1? Thanks jeff (unpacking)
