found this the other day . was wandering how common this is.
I was of the camp that these notes are very common until someone pointed out to me that it depends on the level of misalignment.
Generally what is common is a small misalignment. The type of misalignment shown in the example in the GPM catalogue I have not seen very commonly.
However a vast majority of this type of error notes sold on e-bay that I have seen are of the small misalignment type.
Unfortunately the GPM catalogue does not distinguish between the level of misalignment in cataloging the error and so for collectors it becomes difficult to distinguish.
I do find the level of misalignment shown in GPM catalogue worth collecting. I would not say the same of many of the ones on sale on e-bay.
Perhaps the editors of GPM catalogue should consider adding a note to that cat. no.
I would say a misalignment where the difference between the tops of misaligned and normal numerals is greater than half the height of the numeral should qualify as having some premium. Anything less and it probably would be too common to assign a premium.
