Mexican banknotes... a never ending story... 01 d

So far I wrote about the different designs of the 1-peso note of Mexico, issued between 1936 and 1970.
here you can find the specific differences and how various catalogs deal with them.

Athough I have not mention all possible print dates on the notes yet, I'm still miles away from the more or less 225 possible variations.

No worries, we are getting there...   

First of all, the printing dates, compared to the Pick numbering, as they are less important following DD's system.

Type 1 (DD) :  no date mentioned (issued between 1936 and 1943) - Pick 028a, b, c and d
Type 2 (DD) : 14.VI.1943 - Pick 028e
Type 3 (DD) : 7.VII.1943 - Pick 038a --- 1.IX.1943 - Pick 038b --- 17.I.1945 - Pick 038c
Type 4 (DD) : 12.V.1948 - Pick 038d

Type 5 (DD) : 22.XII.1948 - Pick 046a --- 26.VII.1950 - Pick 046b
Type 6 (DD) : 10.II.1954 - Pick 056a --- 8.IX.1954 - Pick 056b

Type 7 (DD)
    - 19.VI.1957 - Pick 059a
    - ------------- - Pick 059b (deleted)
    - 4.XII.1957 - Pick 059c
    - 20.VIII.1958 - Pick 059d
    - 18.III.1959 - Pick 059e
    - 20.V.1959 - Pick 059f
    - 25.I.1961 - Pick 059g
    - 8.XI.1961 - Pick 059h
    - 9.VI.1965 - Pick 059i
    - 10.V.1967 - Pick 059j
    - 27.VIII.1969 - Pick 059k
    - 22.VII.1970 - Pick 059l  

With a bit of luck a total of 25 different notes are in the above list...

Now two images to explain why there are many more :

2 banknotes type 6 (DD) - Pick 056b

In the image above, two banknotes from the same type 6 - or Pick 056b.
Signatures 1 and 2 are different on both notes, signature 3 is the same.
As a consequense of the different signatures, also the word : CONSEJERO (advisor) has moved.

Type 6 DD - Pick 056b two variations

Another example :

This time, 3 notes from type 7 (DD) - as mentioned earlier, some notes have series with double letter combinations, but these notes have a 3-letter combination.
Date is 10.V.1967 - Pick numbering : 059j 

Type 7 DD - Pick 059j three variations

Although the middle banknote is in poor quality, it is clear, that both signatures 1 and 2 are different on each note, only the last signature is the same on the 3 notes.

It might become clear, that with a little bit of effort, suddenly a wide range of new discoveries lay ahead. 

As it is nearly impossible to list up all signature variations, and from which serial number they start, the most common way (Mexicans) collect these notes, is by looking for series (in the last example BEA, BDK and BDC).
This makes it a lot easier to sort notes, and putting them in alphabetical order, also means, they are sorted by issuing date, as the whole set starts with serie A...
