1 peseta Andorra 1936 (2nd issue) - 2 variants?

Are there 2 confirmed variants of the banknote?

The one that I recently obtained has 6 digits serial number, and O letter in No is few mm lower than in the serial of the banknote posted on Numista, which has 5 digits serial 

Welcome to Numista!

Please provide photos and, ideally, a link to the note in the Numista catalogue (if it's one of those 10).

N#225317

I checked in eBay via pickclick and the two varieties of serial numbers exist, both with the same Pick #6 reference.

This looks like a rare and expensive note. I see there are copies around (some marked COPY others not). Hopefully yours is an authentic one.

I believe so, it was bought from CGB Numismatics
