I purchased 3 £10 and 1 £20 German WW2 Peppiatt counterfeit banknotes recently. Whilst the story of these is told fully on the Pam West website, what I wanted to say was that upon closer examination one turned out to be genuine. The black globes around the Ten....and the watermark line meeting the extreme left serif of the N in BANK and not the centre of N base meant it was genuine. So happy days!
