Banknotes of the third Zimbabwean dollar (ZWR) (printed 2006-2009)

I'd like to know the name of the typeface used to spell out the face values (e.g. [[http://upload.wikimedia.org/wikipedia/commons/3/3e/Zimbabwe_%24100_trill...|ONE HUNDRED TRILLION DOLLARS]]) on the 2007 and 2008 Zimbabwean banknote series. According to [[http://en.wikipedia.org/wiki/Banknotes_of_Zimbabwe#Paper_money_of_the_th...|Wikipedia]], the earliest of these notes were printed in October 2006.

It's a sans-serif outline typeface, and the most distinctive thing about it is that some of the letters (A, [[http://upload.wikimedia.org/wikipedia/en/a/a2/Zimbabwe_%241000000_2008_O...|M]], N and [[http://upload.wikimedia.org/wikipedia/commons/b/bf/Zimbabwe_%2420_2007_O...|W]]) have exaggerated overshoots (with the last three also extending below the baseline). I haven't had any luck with WhatTheFont or Identifont.

Some other examples for the different letterforms:

Comments

Banknotes usually have custom lettering to prevent forgery.

Thanks very much for both of your replies. It looks to me like it's just Futura with a custom border applied - I suppose preventing forgeries isn't a priority during hyperinflation.
