Wertbestandige notgeld are all dated at the end of 1923 and it appears that about 700 places issued them. Those with money values (about 85% of the issues) are either in US dollars and/or Goldmarks or Goldpfennigs. The note above is for a value of 6 goldmarks and was issued by 'Hamburgische Frauenhilfe'. It is catalogued as LSK148, using the new 2002 Hamburg paper money issues catalogue, by Lindman, Stolzenberg & Kirstein.
The notes illustrated below are made of velvet and leather and were issued in Bielefeld and Osterwieck. The leather notes, for 1 Goldmark were issued on different coloured leather. I have green, white, brown and red. All have similar fronts and backs as depicted by the 2 notes shown. I have been told that these Osterwieck notes are Spenden- und Erinnerungsscheine! That is, they are commemerative issues.
The idea behind linking the German currency to the Dollar was that it would hopefully make it more stable and help the German money to maintain a constant value. The following table may help you:
The remaining 15% of wertbestandige notgeld issues are in values of goods such as rye, sugar, water, pure gold, pork dripping, tar, pine timber, Beechwood, wood for burning, safety matches, bricks etc.etc. They seem fairly scarce and are thus, fairly expensive. The note below is from the town of Bad Wildungen and is for the value of 1 cubic metre of beechwood timber. Whatever the inflation rate increased to, this note was always going to have the same buying power.
