...10 to 15 Marks and I don't know how much it was worth in shillings and pence...
As these would be Reichmarks, I don't suppose they were convertible currency during the war ! (I understand the Germans had managed to print millions of very good forgeries of the old white £5 and £10 notes; these they hoped to put into circulation in neutral countries, with a view to ruining the Bank of England). There is supposed to be a giant cache of these notes in sealed containers at the bottom of some Austrian lake to this day.
