The missing circles, from what I can understand, are found on the notes that are on the left edge of a sheet, beginning around the FEE0400000 point and continuing right up until where they currently are stopped (FEN). So, theoretically, about 20-25% of all notes in circulation have the potential to be missing circle notes. The actual number out there is considerably less because if the notes are cut properly, or too far in the other direction, you'll never see the missing circles. You will only see the missing circles on the notes that are cut too far to the left so that they are exposed.
This is not an error by any stretch of the imagination. I am resolved to go with the idea that it is an alignment aid of some kind. This variety is observed on a vast number of banknotes. It is simply an element of the uncut sheet that is a little too close to the cutting region and is regularly exposed.
