A note is either unc or it's not.

True.


A note that's not centred properly is an error note and being an error
makes no difference to the note's grade.

Not true.
Unless its a rather dramatic offset, its pretty much considered a flaw, not
an error.
Same with comic books, baseball cards and stamps.


I would avoid buying from anyone that is offering a note graded higher
than unc as unc is perfect, how can a note be better than perfect?

UNC does not mean perfect.
It means it has not been circulated, or at least show no signs of it.
I fail to see why this concept is so difficult for you to grasp.
You can take two notes fresh off the press, both UNC, and one might be more
appealing to the eye than the other for any number of reasons.
Chances are the will be identical, or you might favor the one on the right,
I might like the one on the left.
Who cares ? The point is is that UNC does not necessarily = perfect.
UNC + UNC Gem implies that it is indeed both uncirculated & perfect.
Which isn't to say that plain UNC can't be perfect, and in any case it will
be in the eye of the beholder to judge.
Its mostly just ebay driven hype I would suppose.
BU is another phrase subject to various interpretations.
I've seen coins with finger smudges all over them advertsied as BU, and
obviously a coin is not uncirculated if it has finger prints on it.


If the guys that print the notes can't print correctly centred notes
they should be sacked.

Obviously, both machines and humans are prone to error now and then.
Considering the vast amount of notes cranked out I'd say they do a pretty
good job - As good as humanly and mechanically possible.


A Scottish note with a centreing error would be regarded as a rare
error.

They probably would be here also if we printed the same number as the
Scots.
I don't know the exact figures, which shouldn't be too hard to obtain.
Say we print 500% more notes than Scotland.
For every note that you print, we print 500.
The probabilty of error is drastically increased, which doesn't take a
genius to figure out.


It would appear that in the USA a properly centred note is regarded as
some kind of exception. Billy


Don't know exactly what point your trying to make here.
Congradualtions, Scotland prints perfect currency.
Don't think you'll win any prize for that, and don't think too many people
outside of Scotland care about Scottish currency.
