The twelve banknotes, one of which had a denomination of five hundred million marks, were part of a 'time capsule' left by August Sieber, an organ builder from Bavaria on 8 January 1930.
The package was found in one of the organ's windchests by restoration experts from Swiss organ company Orgelbau Kuhn.
“The letter and the money weren’t even discovered in 1962, when people from Steinmeyer were in Trondheim to move the organ from the north transept to the west transept,” Per Fridtjov Bonsaksen, who is overseeing the restoration told Adressavisen.
He said the money was accompanied by a message conveying “a bitter and emotional greeting”, warning future generations of the dangers of hyperinflation.
