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

For the 1-peso note, you can choose to collect one note or 225 notes. (see also here)
As it is a low value banknote, and the amount of printed notes is huge (from 1936 till 1970), it should not be too difficult to find a good amount of these notes to compare and collect.

1 peso note overall appearance

As shown above, if one note of each denomination suits you, then one note will do the trick.

Of course this would be a lost of valuable variations to your collection, so let us have a deeper look.
(Images below were taken from the "Guía de Billetes 1925-2019" issued by the Bank of Mexico, as well as from my own collection).
