Possible banknote cutting error [solved]

Hello everyone.

I recently bought some old Spanish banknotes.
I took a closer look at my acquisitions and noticed that one of the banknotes, the 1000 pesetas from 1928, seems to have a small cutting error.

You can see in the bottom left-hand corner the marked borders, which normally shouldn't show, as it should be cut by those marks.

I'd like you to tell me if it's a cutting error or something else, and, if it's a simple cutting error, if it's rare or not to see one with this problem, and if it's more or less valuable because of it.

I'd like your opinion, please.

I would consider these lines printer's guides.  They're common to see & the minor deviation is well within QC tolerances.  

Generally speaking, the older the series the more one sees things like these “guides” & poorly centred notes.  The note in question is actually pretty well-centred considering the guides are showing -so that's a good thing.  This would in no way be considered a cutting error (not close to being dramatic enough).   

All “errors” should be very dramatic or they are considered “poorly produced” (by graders) &  undesirable to many collectors (who seek perfection).  I like notes like the one pictured, but not all collectors do.

Hope that helps.

Thanks for the answer.

I was thinking the same thing, and thank you for clarifying  my question :)
