So far a whole new range of banknotes-to-discover might have caught your attention now.
Trust me, it only get worse.
Did I say 'worse' ... of course I mean 'more interesting'.
As for the higher denominations in this series, it truly gets excited.
But back to the 1 peso.
The original serie start with serie A (and no date) - the last note, issued in July 1970, belongs to serie BIP.
Serie A till Z, makes 26 different series, then followed by AA till AZ, another 26 series, then BA to BZ...
The 'double' letters end with ZZ, and are followed by AAA, where the story restarts, till the final serie BIP.
No higher mathematics are needed, to know that thus there are 62 series A... to BI..., with each 26 letters.
A total of 1612 combinations.
As the last serie ends in BI..P and not in BI...Z, there are 16 combinations less, or 1596....
Helas, not all serie letters were used, some were destroyed (deleted), some just skipped, and who knows, some might not even have been discovered...
I made a grid with a worksheet (if you are familiar with formulas, the grid can be made in less than 5 minutes).
The full grid takes only 2 pages, and can be used for the banknotes that will be topic of future posts.
(Just a waring ... some issued go beyond the BIP serial letters....)
If you are looking for a 1 peso note from series AAA or BBB, or LL, MM, NN, OO, PP, QQ, ... unfortunately they do not exist (or at least they are not mentioned in any catalog).
The use of the I and O is not omitted in this emission.
Although there were no notes printed in series O..., serie IA, IB and IQ till IZ do exist.
In later denominations, those letters were omitted, to avoid being mistaken for 0 and 1.
In the image below, the grid with the existing and non-existing series are visible.
All omitted rows are non-exisiting series.

What is leftover, is about 225 different series to collect.
If you want, you can add a proof note (no serie mentioned, no serial number...) - a specimen note (serial number 00000 and red overprint 'SPECIMEN'.
Finally there is a very rare note with date : 7.VII.1943 (series L) ...
to be continued...
