The £100 note is the scarcest note of the C Series, and the £100 KKK replacement note with KKK
prefix is the only note in the series which is really rare besides the first date £20 note.
I have seen notes in the following regions:
KKK 000001-KKK 004000
KKK 010000-KKK 011603
This leaves a large gap of unobserved notes.
Has anyone seen any outside these number regions?
