Yes, Three Scottish banks issue £100 notes. The RBS, The Bank of Scotland, The Clydesdale Bank issue these notes. However, there are no new £100 polymer notes, as yet. The Bank of England did issue £100 notes but ceased after WW2 due to forgeries. The highest value note in England is £50. I have a good selection of £100 notes for sale…..lovely notes and well worth a perusal.
