Hello Tom,
I know that you collect and specialize error notes. I went through some uncirculated FEK $10 notes this evening, and found one note with no security (fibres) threads on the entire front side (portrait side) of the note. It's a perfect note with not one security thread whatsoever. On the side of the war memorial, only a few security threads are on there.
Because I am so use to seeing notes with security threads, this note looks so unusual to see a "fibre thread-free" note.
First, would this be considered an error note? If so, have you encountered this error before?
Thanks,
Michael
