Call me by your number - 01a Black, red and blue pennies

A penny for your thoughts, but which one...
The 'first' (black) penny is unperforated, and has letters in the bottom corners only.

There were 11 plates, and plate I was divided into plate IA and IB.
It takes a whole study on its own, as the differences are found in the use of different fonts of the alphabet.

1 penny black

The total number of 1p blacks distributed in 1840 is recorded as 63,561,840... this isn't a low number, but in 1840 there were hardly people collecting stamps, and lots of stamps were lost.

2 pence blue

A 2 pence stamp was also issued in 1840.

It has the same features as the 1p, unperforated, letters in the lower corners only -> AA to TL

The total number of 2d Blues recorded as sold in 1840 is 5,382,240. (plates 1 and 2)

This 2p was issued again in 1841, now about 87,960,000 stamps (plates 3 and 4)

1 penny red

Second in line, are the inperforated 1p red pennies.

Total number issued over 2,588,000,000 of which it is estimated 120,000,000 were later perforated, leaving an approximate total of imperforate stamps of 2,468,000,000...

They were printed on plates 1 to 131, but the plate numbers do NOT appear on the stamps.

see link above for the album.

Therefore, I have made a 'basic' album for those who want to collect all letter combinations AA to TL, and another 'basic' album, for those who want to collect all plate number, regardless the corner letters.

I once had the opportunity to see a full reconstruction of a red penny plate. This was collected throughout many years, by one senior member of our stamp club, Peter.

First downloadable documents, are blank album, for all 240 pennies, with letters in 2 lower corners (imperforated).
The reason for this 'odd' number of 240, lies in the fact that till 1971, the imperial system was used.
1 British pound (£),  was worth 20 shillings, and one shilling was 12 pence.
Hence, each row of 12 black/red pennies, was worth one shilling, and all 20 rows together made the cost of one full sheet 1£.

It can be used for black and or red pennies, and also for the blue 2 pence stamps.
As the first stamps had no plate numbers printed on the stamps, it's very hard to compile a full sheet from the same plate.
