I have never really been into collecting banknotes so I am not proficient at grading. The note is crisp but has a noticeable fold down the centre (see image). Would this be considered EF or AU?
My intuition suggests that this is a four-digit radar. Is this correct? Does the fourth (middle) digit influence this classification at all?
Also, apologies for writing over the images. I don't know much about rules governing the uploading of banknote images, so I wrote "do not copy" over them just like how coin dealer listings have "specimen" over theirs.
